Phosphor Bronze is a premier copper-based alloy highly valued for demanding engineering applications. It offers superior elasticity, fatigue resistance, and exceptional corrosion resistance. Hangzhou Target Import & Export Co., Ltd. serves as your trusted B2B partner. We deliver precision-engineered metal materials to manufacturing clients worldwide. Whether you need ultra-thin coils, heavy-duty sheets, or machinable rods, we provide tailored solutions. Our team works to optimize your supply chain and manufacturing efficiency.
Phosphor Bronze is a copper alloy formulated with tin and phosphorus. This specific combination drastically increases wear resistance, fatigue limits, and overall mechanical strength. Procurement departments often face challenges sourcing exact alloy grades across international supply networks. To simplify this process, we supply materials certified to match global standard equivalents perfectly.
Understanding international standards is key to seamless global purchasing. Below is a detailed mapping of popular alloys. This chart shows how Chinese GB standards align with US ASTM and European EN standards.
| UNS/ASTM Grade | GB Standard (China) | EN Standard (Europe) | Primary Characteristics |
|---|---|---|---|
| C51000 | QSn6.5-0.1 | CuSn6 | Excellent spring properties, outstanding fatigue resistance, high ductility. |
| C52100 | QSn8-0.3 | CuSn8 | Superior tensile strength, excellent wear resistance, suited for high-load applications. |
| C54400 | QSn4-4-4 | CuSn4Pb4Zn4 | Outstanding machinability, low friction, high wear resistance. |
Flat-rolled materials are critical for electronics, automotive manufacturing, and precision spring fabrication. We source these products from top-tier Chinese processing plants. This sourcing strategy ensures uniform grain structure, precise thickness control, and excellent flatness. Our supplies easily satisfy the stringent requirements of high-speed progressive die stamping.
We specialize in supplying precision ASTM B103 strips and coils. These are available in custom-cut narrow widths. We provide standard and ultra-thin foil thicknesses to accommodate fine electronic contact stamping. Our engineering team offers various tempers to match your forming requirements perfectly.
| Temper Grade | Primary Properties & Applications |
|---|---|
| Half Hard (H02) | Balanced formability and strength for standard electrical components. |
| Hard (H04) | Enhanced mechanical properties for robust connector pins and clips. |
| Spring (H08) | Maximum elasticity and fatigue life, perfect for precision miniature switches. |
| Extra Spring (H10) | Ultra-high yield strength designed for extreme spring-back applications. |
Our sheets offer exceptional structural integrity for heavy-duty wear plates, thrust washers, and marine hardware. We manage strict flatness tolerances and deliver custom-sheared dimensions. This precision helps you minimize processing scrap and accelerate overall production cycles.
Beyond flat products, we supply solid hexagonal rods, round rods, rectangular bars, and high-ductility wires. These materials are heavily utilized for wear-resistant sleeve bearings and high-durability gear components. They are also ideal for complex electrical spring contacts requiring omnidirectional forming capabilities.
Choosing the correct alloy grade is vital for optimal product performance. Our engineering support team helps you analyze chemical composition and mechanical requirements. We ensure you select the absolute best-fit grade for your project.
As the most popular 5% tin alloy, C51000 balances electrical conductivity and mechanical strength perfectly. Engineers widely specify this grade for electrical terminals, bellows, diaphragms, and switches. It offers outstanding resistance to stress relaxation. Contact our technical team to request a comprehensive datasheet.
Containing approximately 8% tin, C52100 possesses elevated tensile strength and superior wear resistance. We supply this grade for highly stressed spring components, structural diaphragms, and mechanical wear parts. If your project involves heavy-load cyclic stresses, please contact us for detailed mechanical test reports.
C54400 is the industry standard for high-speed machining applications. Adding lead to the alloy matrix achieves a machinability rating of 80% relative to free-cutting brass. It is the premier choice for manufacturing precision sleeve bearings, bushing assemblies, and small gears. This grade is essential where low friction and long service life are critical.
At Hangzhou Target, we do more than simply supply raw materials. We act as an extended arm of your manufacturing operation. Through deep partnerships with modern Chinese processing factories, we offer comprehensive custom processing capabilities. We deliver ready-to-use materials directly to your factory floor.
Our processing partners utilize state-of-the-art precision slitting lines. These machines execute ultra-narrow slitting with extremely tight width tolerances. This advanced tooling ensures completely burr-free edges. Clean edges prevent feeding jams and tool wear during automated high-speed stamping.
We provide tailored surface treatment options to enhance component performance. Electro-tin plating dramatically improves solderability and prevents oxidation in humid environments. We also offer bright polishing and protective oil coatings. These specific finishes are ideal for decorative components or marine-grade parts.
Procuring metal alloys internationally often involves high minimum order quantities and complex logistics. Hangzhou Target bridges this gap by acting as a flexible B2B exporter and coordinator. We combine the manufacturing power of premier Chinese factories with personalized, low-risk procurement solutions.
We offer a unique one-stop procurement service to help you lower inventory costs and bypass high MOQs. You can safely place smaller, specialized orders. We consolidate these orders with other non-ferrous materials like aluminum plates or brass sheets into a single ocean container. This service significantly optimizes your global freight costs.
We maintain rigorous quality assurance protocols to guarantee every shipment meets your specifications. From melt analysis to final dimensions, all orders include official Mill Test Certificates conforming to ASTM and EN standards. We also coordinate third-party inspections through SGS or TÜV. This verifies the chemistry and mechanical properties before dispatch.
Whether you need custom-slit coils, machined rods, or consolidated shipments, Hangzhou Target is your reliable Chinese B2B supplier. Contact our expert engineering team today to request a competitive quote. Partner with a premier Phosphor Bronze manufacturer and exporter to discuss custom processing requirements for your next global shipment.
