Brass and Copper alloys are prized for their exceptional electrical and thermal conductivity, corrosion resistance, and aesthetic appeal. Brass (Copper-Zinc alloy) offers outstanding machinability and is ideal for low-friction applications and decorative parts. Pure Copper is the gold standard for electrical and thermal management components. Partwork utilizes high-speed Swiss CNC machining to produce precise brass and copper components efficiently.
| Property | Specification |
|---|---|
| Electrical Conductivity | Excellent (100% IACS for Copper) – industry standard |
| Thermal Conductivity | Very High (390 W/mK for Copper) – ideal for heat sinks |
| Machinability | Outstanding (Brass C360 is the standard 100% rating) |
| Friction Coefficient | Low (Brass) – excellent for gears and bushings |
| Corrosion Resistance | Good – natural patina forms, does not rust like steel |

Everything you need to know about machining Brass & Copper Machining.
C11000 (ETP) is the standard for most electrical applications (busbars, contacts) with 100-101% IACS conductivity. For specialized applications like vacuum environments or extreme welding, C10100 (OFHC) is preferred to avoid embrittlement, though it costs 20-30% more.
C36000 Brass contains about 3% lead, which acts as a lubricant and breaks chips into tiny pieces. This allows for extremely high machining speeds, low tool wear, and excellent surface finish, making it the lowest-cost material to machine despite the higher raw material cost.
Yes, we can machine lead-free brass alloys (like C46500) for compliance with drinking water regulations (RoHS/REACH), though they are slightly more difficult to machine and material availability in India may vary.
Yes, copper and brass naturally oxidize to form a brown/green patina. If you need to maintain the bright shiny appearance, we recommend Passivation (temporary) or Lacquering/Clear-coating (permanent) surface protection.
Brass is an alloy of Copper and Zinc (yellow, good machinability). Bronze is typically Copper and Tin (reddish-brown, superior wear/bearing properties). Bronze (SAE 660) is the standard for bushings and bearings.
