Product description and main applications
|
Mainly used for Base material with high copper content, easy to weld, good color matching with copper, high conductivity, and also used for welding steel and steel. Preheating is required: 371-538°C, usually argon is used as a protective gas. Phosphorus and silicon are mainly added as deoxidizers, and other elements are added to facilitate welding or to meet the performance of the weld.

Product description and main applications
|
Used for welding of copper-tin Base material, red copper, brass and steel, usually does not require preheating, unless the Base
material has a high copper content. Usually, argon is used as a protective gas. Tin can improve the wear resistance of the weld metal and expand the temperature range between the liquid point and the solid point, thereby increasing the solidification time of the weld metal and increasing the tendency of hot embrittlement. In order to reduce these effects, a small molten pool and fast welding should be adopted. |

Product description and main applications
|
Mainly used for welding aluminum bronze Base material, brass, copper and various dissimilar metals. Generally, preheating is not required, unless the base material contains a high copper content. Generally, argon is used as a protective gas. It is a surfacing material for wear-resistant surfaces that bear lighter loads, a surfacing material for corrosion-resistant media, such as salt or slightly alkaline water, and a common acid-resistant surfacing material that resists various temperatures and concentrations. It is also used Surfacing of wear-resistant and corrosion-resistant surfaces.

Product description and main applications
|
Mainly used for the welding of base materials with similar chemical composition, brass, and these common alloys and steel. It is a silicon bronze containing about 3% silicon and a small amount of manganese, tin or zinc. Welding wire. Used for tungsten electrode gas shielded arc welding and molten electrode gas shielded arc welding, welding copper-silicon and copper-zinc base materials and their welding with steel usually try argon as a shielding gas.
