Our premium Chromium Nickel Silicon Copper (UNS C18000 / CDA 180) is a high-performance, heat-treatable alloy. It delivers exceptional electrical conductivity, thermal performance, and mechanical strength. As a specialized supplier and exporter, Hangzhou Target connects international buyers with prominent Chinese processing mills. We help you source custom-sized metal materials efficiently. This advanced alloy meets the rigorous demands of modern manufacturing. It offers an ideal balance of hardness and conductivity without the health risks of beryllium-bearing alloys.
To accommodate diverse applications, we supply Chromium Nickel Silicon Copper in many semi-finished and finished shapes. Through strategic partnerships with premier Chinese mills, we deliver high-quality materials tailored to exact dimensions. Our standard supply formats include:
Rods and Bars: Round, square, hexagonal, and rectangular profiles ideal for electrode fabrication.
Plates and Sheets: Available in various thicknesses for heavy-duty tooling and mold inserts.
Rounds and Discs: Custom-cut circular blanks designed for specialized resistance welding tasks.
Custom Hollow Profiles: Complex extrusions designed to minimize your downstream machining.
Selecting Chromium Nickel Silicon Copper over traditional C17510 offers significant regulatory, health, and commercial advantages. Beryllium copper has historically been used for high-strength electrical applications. However, it presents severe workplace health risks during machining, grinding, and welding. C18000 is completely beryllium-free. This allows manufacturers to eliminate strict OSHA exposure monitoring and the compliance costs of handling hazardous materials.
Beyond safety, this C18000 alloy provides excellent mechanical properties and high thermal conductivity. It also delivers outstanding wear resistance at elevated temperatures. This makes it a cost-effective, legally compliant alternative that never compromises on performance. We help manufacturers streamline their supply chains while maintaining strict safety standards.
At Hangzhou Target, environmental sustainability and regulatory compliance are integral to our quality assurance. Our materials fully comply with European Union RoHS and REACH directives. Because C18000 contains zero hazardous beryllium, lead, or cadmium, it is a superior choice. It is widely preferred for clean-technology applications in automotive, aerospace, consumer electronics, and medical device manufacturing.
C18000 Chromium Nickel Silicon Copper is highly regarded in the resistance welding industry. It meets the strict classifications of RWMA Class 3 and AWS J1.3. This alloy is heat-treated to achieve optimal hardness and electrical conductivity. This makes it ideal for welding high-strength alloys like stainless steel and monel. Below are the standard properties of our C18000 materials.
| Element | Chromium (Cr) | Nickel (Ni) | Silicon (Si) | Copper (Cu) |
|---|---|---|---|---|
| Nominal Composition (%) | 0.10% - 0.80% | 1.60% - 2.50% | 0.40% - 0.80% | Balance |
| Property | Value (Typical Range) |
|---|---|
| Electrical Conductivity | 38% - 48% IACS |
| Hardness | 90 - 96 HRB (180 - 220 HB) |
| Tensile Strength | 620 - 750 MPa |
| Yield Strength | 520 - 650 MPa |
| Elongation | 12% - 18% |
A primary advantage of Hangzhou Target is our ability to deliver tailored metal processing services. Rather than just supplying raw stock, we work closely with our partner mills. We provide custom-processed Chromium Nickel Silicon Copper near-net shapes. This approach significantly reduces raw material waste. It also minimizes downstream machining times and lowers overall production costs.
Our custom processing capabilities include high-tolerance CNC machining, precision sawing, punching, pressing, and wire-cutting. For applications requiring precise surface finishes, we offer advanced polishing and surface treatments. These controls ensure every piece of C18000 alloy matches your exact engineering tolerances. Your materials arrive ready for immediate assembly or final fabrication.
We leverage stable partnerships with specialized Chinese non-ferrous mills to offer customized industrial extrusions. We can supply custom-formed profiles, bent sections, and unique shapes of this advanced alloy. By managing primary forming steps at the mill level, we bypass middleman markups. This allows us to supply complex components at competitive factory-direct pricing.
Due to remarkable durability and excellent electrical properties, Chromium Nickel Silicon Copper serves many heavy industries. It is particularly valued in high-temperature environments where standard copper alloys would soften or deform. Key industrial applications include:
Resistance Welding: Spot welding tips, seam welding wheels, electrode holders, and projection welding dies.
Plastic Injection Molding: Mold core inserts, cavity inserts, and cooling pins to accelerate heat dissipation.
Electrical & Electronics: High-stress electrical connectors, spring contacts, lead frames, and heavy-duty switchgear components.
Aerospace & Automotive: High-stress wear parts, bushings, and connectors requiring high mechanical strength.
Navigating international metal procurement requires a reliable supply chain partner. You need an expert capable of managing quality, logistics, and technical compliance. Hangzhou Target serves as a trusted global sourcing supplier. We bridge the gap between prominent Chinese mills and international buyers. We mitigate overseas sourcing risks by offering complete transparency and tailored logistical support.
Our strategic relationships with leading non-ferrous mills in China eliminate middleman markups. This enables us to provide direct-to-factory pricing that enhances your bottom line. Different scale operations require different procurement strategies, so we offer flexible terms. We provide prototype sampling for product development and low MOQs down to 300 KGS on stocked materials.
To ensure high-value materials reach your facility in pristine condition, we utilize heavy-duty seaworthy packaging. This prevents oxidation, moisture ingress, and physical damage during intercontinental transit. Our shipments are protected using hermetically sealed plastic wraps, desiccants, and fumigated wooden pallets. This robust protection is combined with rigorous quality control and ISO 9001-compliant processes. We also offer options for independent third-party inspections before export.
Yes, C18000 Chromium Nickel Silicon Copper is a highly effective, beryllium-free alternative to C17510. It works perfectly for most industrial applications. It closely approximates the mechanical strength, thermal conductivity, and hardness of beryllium copper. Transitioning allows manufacturers to eliminate strict regulatory compliance and hazardous waste handling. It removes OSHA safety monitoring requirements, making it a safer and more cost-effective choice.
This high-strength alloy exhibits a moderate-to-good machinability rating, approximately 20% to 30% of free-cutting brass. It can be machined using standard high-speed steel or carbide tooling. However, appropriate cooling and lubrication are recommended to prevent work hardening. For complex geometries, precision wire-cutting or CNC machining produces excellent surface finishes.
For standard stocked shapes and sizes, our minimum order quantity is as low as 300 KGS. For highly specialized custom-extruded profiles or unique alloy specifications, the MOQ depends on negotiable mill-run requirements. We also provide prototype sampling services. This assists engineering teams during the initial product testing and development phases.
We source all materials exclusively from ISO 9001-certified Chinese processing mills. These partners maintain automated processing controls to ensure consistent quality. Every batch is fully compliant with RoHS and REACH standards. We offer full traceability with Mill Test Certificates (MTC). We also support optional third-party inspections before final shipment. As your trusted Chromium Nickel Silicon Copper supplier, we guarantee material excellence. Contact us today to discuss your technical specifications and request a custom quote.
