Bimetal strips from Wenzhou Longsun Electrical Alloy Co., Ltd. are precision-engineered composites of two distinct metals, typically copper and aluminium, permanently bonded to exploit their thermal expansion differentials. The strips maintain a consistent thickness ratio across their length, enabling predictable deflection under temperature change. Standard widths range from 5 mm to 100 mm, with lengths supplied in coils or cut pieces as required by the application.
The material pairing combines the high conductivity of copper with the lightweight and cost-effective properties of aluminium, a configuration typical for electrical contact applications. Surface finishes include bare, tin-plated or nickel-plated to enhance corrosion resistance and solderability. The strips are formed using roll-bonding or explosion welding, methods standard in the industry to ensure a metallurgical bond free of oxides or voids.
These strips are primarily used in thermal protection devices, circuit breakers and relays where reliable thermal activation is critical. Automotive, electronics and renewable energy sectors source them for components exposed to cyclic heating and cooling. Buyers specify coil weight, packaging type and surface treatment to match their production lines, with bulk orders shipped in wooden crates or steel drums for protection during transit.

Wenzhou Longsun Electrical Alloy Co., Ltd. operates from No.181, Weiliu Road in Wenzhou, Zhejiang Province, a region recognised for its concentration of electrical alloy producers. The company’s harbor trust tier reflects a verified business presence and export capability, though its current response rate on the platform is not yet established. The supplier focuses on electrical contact materials, with bimetal strips as a core product line for industrial applications.
The profile does not state certifications, production capacity or year of establishment, so buyers are advised to request these details directly. The address confirms a physical location in an industrial zone, and the supplier’s specialization in electrical alloys suggests a narrow, technical product range rather than a broad catalog. No additional claims about scale, clients or quality systems are provided in the available data.

Before ordering, verify the exact material composition and thickness tolerance of the strips, as these determine thermal deflection and mechanical fit. Request a material test report to confirm the copper-to-aluminium ratio and bonding integrity, as inconsistencies can affect performance in critical applications.
Confirm logistics details such as packaging type, coil weight and port of loading, as these impact shipping costs and handling. Standard Incoterms for bulk metal shipments include FOB or CFR, with payment typically arranged via T/T or L/C. Lead times may vary based on order volume and production scheduling.
Inspect incoming material for surface defects, dimensional accuracy and bonding quality using calipers and visual checks. For high-precision applications, perform a sample test to measure deflection under controlled temperature change. Request a certificate of conformance to ASTM B864 or equivalent to ensure compliance with industry standards.
