This is a low temperature easy welding rod. It is made of aluminum material, durable to use. Low melting point and no extra flux required design can provide convenience for your welding work. Can weld almost all white metals, including aluminum, aluminum alloy, cast aluminum, aluminum-magnesium alloy, etc. Features - Material: Aluminum. - Size: 33.00X0.16X0.16cm/12.97X0.06X0.06in. - Through cleaning physical, polishing the surface before welding. Only use a metal brush to melt the welding wire to fill the weld to form a weld. - Heat the surface of the base metal at the welding place until the temperature reaches the working temperature of the welding wire 380 degree centigrade-400 degree centigrade, so that the welding wire can be melted by the heat conduction of the base metal to form a weld. - Do not use flame to burn the welding wire. When the surface temperature of the material is sufficient, the welding wire can flow and penetrate into the metal capillary well. - When repairing thinner aluminum, just heat the aluminum base material to a suitable working temperature, and then use the welding wire to friction and fuse to form a weld. - Use gas to weld small parts, and large parts are heated and welded with industrial gas or induction heating device. Naturally slow cooling after welding. Package list: 10 x welding rods
