Copper alloys: Common copper alloys are brass, bronze and white copper.
Aluminum alloy: According to the composition of aluminum alloy and the characteristics of production process, it is usually divided into two major categories: deformation and cast aluminum alloy. Industrial applications are mainly aluminum-manganese, aluminum-magnesium, aluminum-magnesium-copper, aluminum-magnesium-silicon-copper, aluminum-zinc-magnesium-copper alloys. The deformed aluminum alloy is also called cooked aluminum alloy. According to its composition and performance characteristics, it is divided into five kinds of rust-proof aluminum, hard aluminum, super-hard aluminum, wrought aluminum and special aluminum.
Lead-based alloy: The lead-based bearing alloy is a lead-bismuth-tin-copper alloy, which has moderate hardness, good running-in property, slightly larger friction coefficient, and low toughness. Back to this, it is suitable for casting bushes that are less subject to shock, lighter loads or slower speeds.
Nickel alloy: Nickel can be combined with copper, iron, manganese, chromium, silicon and magnesium to form a variety of alloys. Nickel-copper alloy is a famous Monel alloy. It has high strength and good plasticity. It has stable chemical properties in the atmosphere below 750 °C. It is widely used in electrical industry, vacuum tube, chemical industry, medical equipment and marine shipbuilding industry.
