Copper strips are favored for soldering, as an embedded part, or for other assembly processes to achieve optimal electrical performance.
Aluminum
Aluminum is used as a base material for a jumper terminal strip to provide a lightweight and affordable substitute to copper. Although aluminum has lower electrical conductivity than copper, its strength-to-weight ratio and high tensile strength make it suitable for giant structures like power grids and overhead lines. It is: usually coated with an additional layer of metal, such as nickel or tin, to prevent oxidation and enhance conductivity. Aluminum strips are widely used in outdoor, marine, and power distribution activities to give a combination of lightness and cost-effectiveness.
Brass
Brass, an easily malleable copper-zinc alloy, is popular for manufacturing jumper terminal strips because of its moderate-level conductivity anti-corrosion features. It is treated and finished with parts that are subjected to frequent connections and disconnections since it withstands tarnishing and oxidation. Due to these properties, it makes an ideal jumper terminal strip for marine environments, electronic equipment, or any application where durability and corrosion resistance will be required. Besides, brass is inexpensive and easy to machine, which adds to its appeal for manufacturers.
S stainless Steel
Stainless steel is a galvanized iron and carbon alloy with chromium and other metals in its concentration, thus corrosion-resistant. Although it has lower electrical conductivity than copper and brass, stainless steel is ideal in harsh environments that require high temperatures and chemical exposure. It is: very hard, does not corrode or wear easily, making it suitable for applications that need strength and durability. Stainless steel strips are commonly used in industries: such as chemicals or food processing and manufacturing equipment.
Tin-Plated Steel
Tin-plated steel jumper terminal strips combine conductivity and affordability. Tin's resistance to corrosion is provided with the strength and low cost of steel. Tin has excellent solder-ability and oxidation resistance, making it ideal for electronic applications requiring cost-effective, dependable solutions. Automotive, electronics, and other industries where environmental protection and soldering are required are examples of places where these strips work well.
