450g 3/32inch Gold Silicon Bronze Tig Welding Rods 91cm Long Rod 2mm Diameter 50000PSI

Description Silicon Bronze is a copper based filler metal containing about 3 silicon and may have small percentages of manganese tin and zinc Silicon bronze is typically used for gas tungsten arc welding and gas metal arc welding of copper brass bronze steel galvanized steels and also cast iron When working with silicon bronze base metal keep the interpass temperature below 150 F to minimize hot cracking Base metals of cast iron may need a preheat of 600F while copper may need a 400 800F The use of a small narrow weld puddle will reduce the contraction stresses and give you a faster cooling during the hot short temperature range May also be known as Everdur Specifications Model S221Color CopperMaterial Silicon BronzeDiameter 2 0mmLength 91cm 35 8Melting point 965 1035℃Typical Composition 1 0 Zinc1 5 Manganese3 4 Silicon0 5 Iron1 0 TinTrace amounts of Aluminum and Lead92 5 CopperProperties Tensile Strength 50 000PSILiquidus Melting Point 1 880FPurpose silicon bronze brass and its welding with steel brazing of galvanized steel sheet Package Included 1 x 450g Silicon Bronze TigDetail Pictures
