Description
Copper has excellent electrical conductivity, thermal conductivity, ductility, corrosion resistance, wear resistance and other excellent properties, and is widely used in electric power, electronics, energy and petrochemicals, machinery and metallurgy, transportation, light industry and other fields. So what are the specific processing techniques for copper? Commonly used techniques by H&G Precision include: CNC processing, milling machine processing, lathe processing, grinder processing, wire cutting, EDM, etc. Each process is equipped to provide more complete services, saving you time and worry!
What industries are CNC machined copper parts suitable for?
CNC processed copper parts are generally suitable for: bathroom hardware, gears, bearings and turbine blades, power generation equipment, rail transit motors, control systems, electrical systems and signaling systems, aerospace, electronic communications, home appliances, automobiles and other industries. If you have high requirements on the physical properties of your product materials, copper will be a good choice for you.
What surface treatments can be done on CNC processed copper parts and small batch customization?
Since copper is a very reactive metal, it is easily affected by the environment. If it is in a humid or special environment, it is easily oxidized, resulting in spots on the surface and even patina, which greatly reduces the appearance of the product. H&G Precision can provide supporting surface treatment services after CNC processing copper parts: such as copper passivation, electroplating, etc.
Passivation: As we all know, passivation has the effect of preventing oxidation and corrosion. Therefore, passivation treatment of copper parts can effectively protect the surface effect of copper parts.
Electroplating: Copper parts have very good conductivity and have the best electroplating effect among all hardware materials. Electroplating can also enhance copper’s corrosion resistance, increase hardness, prevent wear, improve conductivity, smoothness, heat resistance and beautiful surface.

Copper and copper alloy classification habits are generally divided into four categories according to color:
1. Red copper: pure copper, also called red copper, with a density of 8.96 and a melting point of 1083°C. Commonly used grades: T1, T2, T3, TU1, TU2. It is often used in electrical switches, electronic parts, etc., and has good conductivity. And thermal conductivity, excellent plasticity.
2. Brass: An alloy based on copper and zinc. Commonly used grades: H59, H62, H65, H68, HPb59-1. It has good cold working properties, high strength and resistance to seawater corrosion. It is often used in ships. Corrosion-resistant parts are also often used as watch parts, valves, pipe fittings, etc.
3. Bronze: refers to copper alloys other than copper-nickel and copper-zinc alloys. Commonly used grades: B19, B25, BF have 0-1-1, BZ Civilian Police-20, BA13-3. It has good anti-friction and mechanical properties and is suitable for Suitable for manufacturing bearings, worm gears, gears, bushings and other high-load parts.
4. White copper: a copper alloy with nickel as the main added element; good mechanical properties and corrosion resistance, beautiful color, and good thermoelectric properties. It is widely used in the manufacture of precision instruments, medical equipment, chemical machinery and ship parts, watch parts, etc.
Although copper has different material grades, at H&G Precision, there is no need to worry about raw material issues. Before each product is processed, professional colleagues from the quality department will use a spectrometer to test the raw materials and confirm that the raw material components are qualified before arranging production. This adds another level of assurance to the quality.
