Product Description
The Solid Premium Brass Rod Wire for Machinery stands as a benchmark engineering material tailored to meet the rigorous demands of industrial machinery and precision component manufacturing. Forged from lead-free brass alloys (notably C3602 and C3771), these rods and wires strike an exceptional balance between high machinability, corrosion resilience, and structural robustness. Unlike traditional leaded brass, their lead-free composition aligns with global environmental regulations (such as RoHS and REACH), making them suitable for industries prioritizing sustainability without sacrificing performance. Ideal for applications requiring consistent tensile strength and wear resistance, they have become indispensable in automotive, aerospace, and heavy machinery sectors.
Parameter | Value |
Alloy Type | C3602, C3771 |
Diameter Range | 3–200mm (rods); 0.5–20mm (wires) |
Tensile Strength | 370–420MPa |
Hardness | 72–85 HBW2.5/187.5 |
Surface Finish | Bright annealed, polished |
Precision Machinability: C3602 brass rods excel in high-speed CNC machining, with excellent chip control that reduces tool wear by up to 40% compared to steel. This allows for intricate manufacturing of gears, bushings, and valve components with surface tolerances as tight as ±0.01mm.
Superior Corrosion Resistance: The lead-free alloy formulation forms a protective oxide layer that resists oxidation, moisture, and chemical exposure—even in marine environments or industrial settings with frequent coolant contact.
High Strength-to-Weight Ratio: At 8.4g/cm³, these brass rods are 30% lighter than steel while maintaining a load capacity of 20–50MPa, making them ideal for lightweight yet durable components in rotating machinery.
Thermal Stability: Withstands continuous operating temperatures up to 250°C without significant loss of mechanical properties, ensuring reliability in engine compartments and high-heat industrial processes.
Automotive Industry: Critical for fuel injectors, transmission bearings, and hydraulic valve bodies, where their anti-seizing properties and resistance to engine oils extend component lifespan by 30%+.
Aerospace: Used in aircraft hydraulic fittings, sensor connectors, and actuator components, meeting stringent aerospace standards (e.g., SAE AMS 4611) for fatigue resistance and dimensional stability.
Industrial Machinery: Valves, pumps, and precision tooling benefit from the rod’s low friction coefficient (0.15–0.2) and ability to maintain performance under heavy cyclic loads.
Medical Equipment: Employed in sterilizable components like surgical instrument housings, leveraging lead-free compliance and easy sanitization.
Q: Can these rods be welded?
A: Yes, TIG or MIG welding with ERCuSi-A filler wire ensures strong joints while preserving corrosion resistance. Pre-weld cleaning with stainless steel brushes is recommended to remove oxide layers.
Q: What is the recommended machining speed?
A: For C3602 brass, optimal turning speeds range from 80–120 m/min with carbide tools, using water-soluble coolants to prevent chip buildup and maintain surface finish.
