The rivet contact has two forms: a nail head layer and a double layer at both ends. The composite material may be made of silver, gold, palladium, platinum or alloy materials. The matrix is generally pure copper with good plasticity and conductivity, and the precious metal material is only Composite in the necessary position for electrical contact of the contacts.

     Therefore, the precious metal is effectively saved, the cost of the contact is reduced, and the sustainable development of the society is realized. The working layer material is more flexible than the overall precious metal rivet material selection, because the precious metal alloy material, although having excellent electrical contact properties, is not suitable for making the integral rivet contact due to poor riveting processability, and the rivet contact can be used to lengthen and avoid short. The plating of precision screws generally refers to the precision screws of iron. Stainless steel precision screws generally do not need to be electroplated unless requested by the customer. Precision screw plating colors are environmentally friendly and non-environmental. Non-environmental precision screw plating colors are color zinc, white zinc, black zinc, black, white nickel, black nickel, blue zinc and so on. Environmentally-friendly precision screw plating color is environmentally friendly color zinc, environmentally friendly white zinc, environmentally friendly blue zinc, environmentally friendly black zinc, environmentally friendly nickel, environmentally friendly black zinc and so on. The precision screws are made of iron and stainless steel. The precision screws of iron are usually made of iron wire rods. The materials are low carbon steel, medium carbon steel and high carbon steel. Screw wire has 1010A, 1018, 10B21, 45 steel and so on. Stainless steel chemical anchors are generally made of stainless steel screw wire piers. Its material is stainless steel SUS201, stainless steel SUS304.

    Stainless steel SUS776, stainless steel SUS316, stainless steel SUS404 and so on. If the precision screws are required to be higher, the hardness of the precision screws on the product materials is generally required to be hardened. Because many precision screws that are not hardened are easy to slip when using the material.
