Zinc alloy: The main added elements of zinc alloy are aluminum, copper and magnesium. According to the processing technology, zinc alloy can be divided into two types: deformation and cast zinc alloy. Cast zinc alloy has good fluidity and corrosion resistance, and is suitable for die-casting instruments, automotive parts and the like.
Magnesium alloy: The alloying elements in the magnesium alloy are mainly aluminum, zinc and manganese, and sometimes a small amount of zirconium, hafnium, tantalum and the like are added. Magnesium alloys can be divided into two major categories, deformation and cast magnesium alloy, depending on the production process. Magnesium alloy is an important lightweight structural material widely used in aviation and aerospace industries.
Titanium alloy: Titanium alloy can be divided into three types according to the structure (aluminum and tin are added to titanium; alloying elements such as aluminum, chromium, molybdenum and vanadium are added to titanium; elements such as aluminum and vanadium are added to titanium.) Titanium alloy has high strength and low density. Good mechanical properties, good toughness and corrosion resistance. In addition: the process performance of titanium alloy is poor, and the cutting process is difficult. In thermal processing, it is very easy to absorb impurities such as hydrogen, nitrogen, nitrogen and carbon. There is also poor wear resistance and complicated production processes.
Tin-based alloy: The tin-based bearing alloy is a tin-bismuth copper alloy. It has a small coefficient of friction, moderate hardness, good toughness, good running-in, corrosion resistance and thermal conductivity, and is mainly used for bearing bushes working under high speed and heavy load conditions.
