Beryllium copper (BeCu), also known as copper beryllium (CuBe), beryllium bronze and spring copper, is a copper alloy with 0.5—3% beryllium and sometimes with other alloying elements. Beryllium copper combines high strength with non-magnetic and non-sparking qualities. It has excellent metalworking, forming and machining qualities. It has many specialized applications in tools for hazardous environments, musical instruments, precision measurement devices, bullets, and aerospace.

OXYGEN FREE COPPER

Oxygen-free copper (OFC) or Oxygen-free high thermal conductivity (OFHC) copper is a group of wrought high conductivity copper alloys that have been electrolytically refined to reduce the level of oxygen to .001% or below.

CADMIUM COPPER

Cadmium copper alloys are considered high copper alloys, they contain approximately 98 - 99 % copper, 0.1 - 1.5% cadmium. When cadmium is added to copper the material becomes more resistant to softening at elevated temperatures. The more cadmium that is added the more heat resistant the material becomes.  Cadmium copper is used in applications such as trolley wire, heating pads, electric blanket elements, spring contacts, connectors, and high strength transmission lines.

LEADED COPPER

The role of lead in copper alloys is two fold, it acts as a lubricant and, in the free machining grades, the lead assists in chip break up. The size and concentration of lead particles depends upon the concentration of lead in the alloy. Leaded coppers are categorized as low lead alloys, or free machining alloys and high lead alloys.

Chromium copper alloys are high copper alloys, containing 0.6 to 1.2% Cr.  Chromium copper has excellent cold formability and good hot workability. It is used in applications such as resistance welding electrodes, seam welding wheels, switch gears, cable connectors, circuit breaker parts, molds, spot welding tips, and electrical and thermal conductors that require strength.

COPPER NICKEL

Copper nickel alloys are very corrosion resistant and thermally stable. The copper nickel alloys contain from 2 to 30% nickel depending upon the application. They are virtually immune to stress corrosion cracking and exhibit high oxidation resistance in steam and moist air.  The copper nickel alloys are used in applications such as electrical and electronic products, tubes for condensers in ships and power plants, various marine products including valves, pumps, fittings and sheathing for ship hulls.
