Special fasteners
With the continuous development of the industry, various requirements for metal materials are becoming more and more stringent. In order to meet the special needs of different working conditions, many special materials have emerged. The special materials provided by our company mainly refer to super stainless steel, titanium alloys, nickel-based alloys, copper-nickel alloys, cobalt alloys, NASA AMS high-performance materials, etc. For this type of fasteners, we mostly directly use the imported finished fasteners or the imported raw materials for domestic production. Most of our raw materials or fasteners come from the United States, Britain, Germany, France, Finland and other countries. The specific material grades are as follows:
