Welding wire designated as 1100 contains between 0.05 and 0.20 percent copper, 0.05 percent manganese and 0.10 percent zinc. By comparison, 5356 welding wire typically consists of between 4.5 and 5.5 percent magnesium, between 0.05 and 0.20 percent manganese, between 0.05 and 0.20 percent chromium and between 0.06 and 0.20 percent titanium.
Tensile strength refers to the amount of stress a material can bear before tearing. Using 1100 welding wire results in the creation of a weld that can withstand pressures in the 13,500 psi (pounds per square inch) range. The tensile strength of 5356 welding wire offers a 38,000 psi pressure capacity.
Welding wire rated at 1100 has a melting range of between 1,190 and 1,215 degrees Fahrenheit, while 5356 welding wire offers a melting range between 1,060 and 1,175 degrees Fahrenheit. The density of 1100 wire is 0.098 lbs. per cubic-inch (lbs/ci), while the density of 5356 welding wire is 0.096 lbs/ci.
