10 PCS 2.0MM 50CM Low Temperature Aluminum Welding Wire, Convenient Durable Al Soldering Rod No Need Solder Powder

• 【Wide Application】This kind of low-temperature aluminum welding wire can weld almost all white metals, including aluminum, aluminum alloy, cast aluminum, aluminum-magnesium alloy and so on. It has high strength, good forgeability & good corrosion resistance.
• 【Feature】The aluminum alloy that someone think it is irreparable can be repaired, even white metals that have been seriously corroded or contaminated with oil.
• 【Great Welding Effect】With full & smooth welding effect because of internal powder. With low melting point, great weldability and corrosion resistance, high thermal conductivity, high electric conductivity and excellent processing performance.
• 【Easy to Use】It is suitable for all-round welding of the primary welding operator. It only needs a small heating device. The weld strength after welding is generally higher than the strength of the base material itself. You don't have to use other flux powder with aluminum alloy as the welding core and coating as the salt base. Very convenient and easy to weld.
• 【More Details】Material: Aluminum silicon; Specifications: Diameter 2.0mm, each 50cm long; Melting point: 450 degrees Celsius or above.

Product Information: Specifications: diameter 2.0mm, each 50 cm long Instructions: Step 1: Polishing the surface by physical cleaning. Step 2: Heating the surface of the base metal until the temperature reaches the working temperature of the welding wire of 450 ° C or above, so that the weld can be formed by the heat conduction welding wire of the base metal, and the flame welding wire should not be used, and only when the surface temperature is sufficient The wire can flow and penetrate well. Step 3: When repairing relatively thin aluminum, just heat the aluminum to a suitable working temperature, and then use a wire and a metal brush to rub back and forth to form a weld. Attention: 1. The surface must be cleaned up. 2. The temperature of the base metal should be kept at 450 °C during the welding process, and the temperature can not be lower. 3. Avoiding using flames to deliberately burn the wire, after the temperature reaches 450 ° C, the wire will naturally rely on the thermal conductivity of the base material.
