1100 is formed by adding a small amount of copper element to pure aluminum, which has excellent forming processing characteristics, high corrosion resistance, good weldability and electrical conductivity. Widely used in products that require good formability and high corrosion resistance, but low strength requirements, such as chemical equipment, food industry equipment and storage containers, cooking utensils, pressure tanks, thin sheet processing, deep drawing or spinning concave Containers, welding parts, heat exchangers, clock surfaces and plates, nameplates, kitchen utensils, accessories, hardware, reflectors, etc. Chemical Composition Limits wt% Typical Alloy 1100-H14 Mechanical and Physical Properties (Typical Mechanical & Physical Properties) The square nut is one of the welding nuts. The welding method is believed to be known to all. It is to use high temperature to melt some metal and weld it between the two products to play a fastening role. The fastening effect of this connection will be very good and will not be easy to loosen. It can also be used with bolts. Square nuts are mainly used in electric power engineering, road traffic, home building materials and other industries.
