Tungsten Copper
Tungsten copper is a composite of tungsten and copper, typically with 50% to 90% tungsten. It combines the high melting point, hardness and arc-erosion resistance of tungsten with the high thermal and electrical conductivity of copper, and has a low rate of thermal expansion.
Key Properties
- High resistance to arc erosion and welding
- Good thermal and electrical conductivity
- Low thermal expansion
- High density and hardness
Applications
- EDM and resistance-welding electrodes
- Electrical contacts for high-voltage switchgear
- Heat sinks and thermal-management parts
- High-temperature components
Beryllium Copper
Beryllium copper is a precipitation-hardening copper alloy containing a small amount of beryllium. After age hardening it reaches the highest strength of any copper alloy while keeping good electrical and thermal conductivity. It is non-sparking and non-magnetic.
Key Properties
- Very high strength and hardness after heat treatment
- Excellent fatigue and spring properties
- Non-sparking and non-magnetic
- Good conductivity and corrosion resistance
Applications
- Springs, connectors and contacts
- Bushings and bearings for heavy loads
- Non-sparking safety tools
- Moulds for plastics and welding components
Chromium Zirconium Copper
Chromium zirconium copper is a heat-treatable copper alloy with small additions of chromium and zirconium. It offers high electrical and thermal conductivity together with good strength, and resists softening at elevated temperatures.
Key Properties
- High electrical and thermal conductivity
- Retains hardness at high temperature
- Good wear resistance
- Long electrode life
Applications
- Resistance-welding electrodes, caps and wheels
- Seam-welding and spot-welding parts
- Continuous-casting moulds
- Electrical and heat-exchange components
Tellurium Copper
Tellurium copper contains a small addition of tellurium that makes it free-machining, while keeping electrical and thermal conductivity close to that of pure copper. It is well suited to precision parts made on automatic machines.
Key Properties
- Excellent machinability
- High electrical and thermal conductivity
- Good corrosion resistance
- Good hot-working properties
Applications
- Precision-machined electrical parts
- Connectors, terminals and switch parts
- Welding torch tips and nozzles
- Fasteners and screw-machine parts
Manganese Bronze
Manganese bronze is a high-strength copper-zinc alloy with additions of manganese, aluminium and iron. It combines high tensile strength and hardness with good wear resistance and resistance to seawater corrosion.
Key Properties
- High tensile strength and hardness
- Good wear resistance under heavy loads
- Resistant to seawater corrosion
- Good castability
Applications
- Marine propellers and fittings
- Heavy-duty bearings and bushings
- Gears, valve stems and hydraulic parts
- Structural and machinery components
Silicon Bronze
Silicon bronze is a copper alloy with around 3% silicon. It has excellent corrosion resistance, good strength and toughness, and is easy to weld, braze and cast.
Key Properties
- Excellent corrosion resistance, including in marine conditions
- Good strength and toughness
- Easy to weld, braze and cast
- Attractive finish
Applications
- Marine hardware and fasteners
- Pump and valve components
- Electrical hardware
- Architectural and decorative parts
