Application.
  For valves which size is smaller than 2"(DN50), forged steel valves are recommended. Compared with castings,forged valve offer the advantages of more uniform structure, greater density, higher strength integrity, enhanced dimensional characteristics and closer dimensional tolerances.Owing to so many advantageds,the forged valve can be widely used in the fields of petroleum,natural gas,chemical,power and other industries.   Â

Aluminum Color Coated Sheet is Aluminum Sheet with color coated on one side or two sides.It is widely used in construction areas.It is light in the weight and easy to be recycled.Also with the color coating,the surface is good looking and has longer life in corrosion resistance.Aluminum Color Coated Sheet has more advantage as follows:
1. Easy to process.
The results show that the casting aluminum alloy with good casting property or deformation aluminum alloy with good processing plasticity can be obtained by adding certain Ba Au Du element.
2. Good conductivity and thermal conductivity.
The electrical and thermal conductivity of aluminum is second only to silver, copper and gold.
3. The density is small.
The density of aluminum and aluminum alloy is close to 2.7 g / about 1 / 3 of that of iron or copper.
4. High strength.
The strength of aluminum and aluminum alloy is high. The matrix strength can be strengthened by cold working to a certain extent, and some brands of aluminum alloy can also be strengthened by heat treatment.
5. Good corrosion resistance.
The surface of aluminum is easy to produce a dense and firm protective film of Al2O3, which can protect the substrate from corrosion.
