Product Feature

Powder copper alloys refer to copper alloys that are directly formed from copper powder and other metal powders by powder metallurgy technology. Copper alloy powder metallurgy sintered parts metal powder can be directly made into various shapes of products or parts without cutting or only a small amount of cutting. The traditional processes are: milling, mixing, pressing, sintering, etc.

1. Cu-l10Fe-5Sn-5Pb-8C

-3SiO2-3MoSi alloy

It has good physical and mechanical properties, good cutting and wear resistance, sufficient friction coefficient and friction coefficient stability, simple process and low price, mainly used for brake materials.

2. Cu-50W alloy

It is formed by mixing powder sintering method or re-pressing method. The alloy has: high strength and hardness, good electrical and thermal conductivity, wear resistance, fusion resistance, and arc burn resistance. , EDM electrode.

3. Cu-50Cr alloy

Solid-phase sintering is used to make the billet reach a certain density (relative density > 80%) and strength, and then deformed by hot working to achieve complete densification. Hot extrusion, hot pressing or hot forging can be used, and the processing temperature is generally lower than the melting point of copper. 100℃, after processing, the material is vacuum annealed at 500~600℃ to relieve stress and degas. The alloy has good electrical and thermal conductivity, anti-melting, anti-arc burnout, and is used for vacuum switch appliances.

4. Cu-AI2O3 alloy

Oxide dispersion strengthening (ODS) was used. The alloy has high strength, electrical and thermal conductivity, especially high softening resistance and recrystallization temperature. Suitable for electrodes, X-ray tubes, microwave tubes, hybrid circuit packages, commutators, switch components, etc. of resistance welding machines.

Post Casting Process

1. Heat treatment: annealing, carbonization, tempering, quenching, normalizing, surface tempering

2. Processing equipment: CNC, WEDM, lathe, milling machine, drilling machine, grinder, etc.;

3. Surface treatment: powder spraying, chrome plating, painting, sandblasting, nickel plating, galvanizing, blackening, polishing, bluing, etc.

Moulds and Inspection Fixtures

1. Mold service life: usually semi-permanent. (except for lost foam)

2. Mold delivery time: 10-25 days, (according to product structure and product size).

3. Tooling and mold maintenance: Zhongwei is responsible for precision parts.

Quality Control

1. Quality control: the defective rate is less than 0.1%.

2. Samples and trial run will be 100% inspected during production and before shipment, sample inspection for mass production according to ISDO standards or customer requirements

3. Testing equipment: flaw detection, spectrum analyzer, golden image analyzer, three-coordinate measuring machine, hardness testing equipment, tensile testing machine;

4. Provide after-sales service.
