Name: S201 coppers welding wire
Composition: Cu≥98.0%; Sn≤1.0%; Si≤0.5%; Mn≤0.5%; P≤0.15%; Al≤0.01%;
Uses: S201 contains a small amount of tin, silicon, manganese, phosphorus and other deoxidizing elements of special copper welding wire, melting point of 1020-1050 °C, silicon, manganese, phosphorus is mainly added as deoxidizer, and tin is added to improve the fluidity of copper. It has the characteristics of excellent welding process performance, beautiful weld forming, high mechanical properties and good crack resistance.

Uses: useds for argon arc welding, gas welding and plasma arc welding of copper, such as billet continuous casting crystallizers, electrode fixtures in steel mills, conductive rollers, conductive plates, heating elements, copper containers, copper sculptures, etc.

Name: S211 silicon bronze welding wire（ Si BronzeWeldingWire）
Composition: Si=2.8-4.0%; Mn=0.5-1.5%; Cu margin.
Description: Bronze welding wire containing 3% silicon and a small amount of manganese, with a melting point of 965-1035 °C, excellent welding process performance and high mechanical properties of the weld.
Uses: It is useds for argon arc welding of silicon bronze, brass and copper and steel, brazing of galvanized thin steel plate, and can also be useds for surfacing welding of steel and cast iron.

Name: S214 Aluminum bronze welding wire（ Al Bronze WeldingWir）
Composition: Al=7.0-8.5%; Fe≤0.5%; Cu margin.
Description: S214 is an iron-free aluminum-bronze welding wire with a melting point of 1030-1040 °C, which can resist light load wear, seawater and corrosion of commonly useds acids.

Uses: It is suitable for the surfacing welding of aluminized steel plates, marine propellers, slide rails, sliding surfaces and bearing surfaces, as well as the connection welding and surfacing welding of gray cast iron in the machinery manufacturing industry, shipbuilding industry, and the welding of corrosion-resistant aluminum bronze or brass.

Name: S221 Tin brass welding wire（ Tin BrassWeldingWire）
Composition: CU=59-61%; Sn=0.5-1.0%; Si=0.15-0.35%; Zn margin.
Note: S221 has a melting point of about 890-905 °C and is a special brass wire containing a small amount of tin and silicon. Tin can improve the fluidity of the wire, while silicon can effectively control the evaporation of zinc and eliminate porosity, resulting in a good weld.

Uses: It is suitable for brass and copper gas welding as a filler material, and is also widely useds in brazing steel and cast iron and inlaid carbide tools. It can also be useds as a surfacing material for the sealing surfaces of low-pressure valves and light-load wear-resistant surfaces.

Applications:Professional welder, metalworking hobbyist, or DIY enthusiast, this MIG wire gives you the freedom to work on multiple projects.
