When this material is used as a general resistance welding, the treatment methods of this material after oxidation are as follows. The vinegar so...Read more -
Selection of annealing process for tin bronze sheet
The phase transition temperature of tin bronze sheet from α→α+ ε is about 320 ℃, that is, the heating temperature is higher than 320 ℃, the structure is single-phase structure, until heated to 930 ℃ or so liquid phase structure, considering the use of equipment, the degree of oxidation of the wor...Read more -
The advantage of copper tube
1. Safe and reliable: copper tube integrates the advantages of metal pipe and non-metal pipe. It is harder than plastic pipe, with the high strength of general metal (cold drawn copper pipe strength and the same wall thickness of steel pipe); It is more flexible than ordinary metals, good toughne...Read more -
Carving brass sheet chemical polish use method and matters needing attention
Compared with mechanical polishing and electrochemical polishing, chemical polishing of brass does not need electricity and hanging tools. Therefore, it can polish the carved brass sheet with complex shape, and the production efficiency is high. The bright surface is obtained by chemical polishin...Read more -
Milling surface quality of brass strip hot rolling process
