1. What is clad strips:

    Clad strips are metal materials with different characteristics that are joined into new functional materials using advanced joining technology, which not only retains the material properties, but also gives full play to the comprehensive performance resulting from the joining. Materials selected for joining based on different electrical load ranges, chemical properties and material properties are widely used in the industry.

2. Composite material supply types and introduction

    Composite materials are divided into three types: layered clad strips, special-shaped clad strips, multi-component stamping components (materials for metal dome, special-shaped contacts, button contacts, etc.)

    (1) Layered composite materials:

    ① Ideal and suitable connection materials: alloy materials that can be used to match the application, and precious metals to replace high-grade gold layers;

    ② Favorable stamping costs: For connecting products made of clad strips, the stamping and bending processing are realized by only one production process;

    ③ Optimum adhesion: During the cladding process, the bonding parties enter the metallurgical connection, and the alloy one-piece material with superior joint strength is used;

    ④ Excellent ductility: no cracks will occur during production processes such as stamping;

    ⑤ Free parameters: Freely select width, thickness, shape, multi-strip inlay and multi-layer jointed alloy composite materials.

    (2) Special-shaped composite materials:

    ① Overview: The material is a micro, special-shaped composite material that is closely combined with the electrical contact material and the load-bearing material through a unique skin effect process (its cross-section is irregular, mostly in special shapes such as triangles and trapezoids); it not only protects the materials’ own performance from destroyed, and the comprehensive performance generated by the combination effect is fully exerted; the bonding strength between each layer of the material is high and stable.

    ② Related applications and commercial advantages: It can effectively reduce the production process and meet the requirements of automated production; It can be single-layer, two-layer or multi-layer special-shaped composite materials; It can realize the miniaturization of electrical products and meet the trend of miniaturization, lightweight and high integration of electrical products.

3. Product features:

    ① We can design and manufacture composite materials with optimized mechanical properties and electrical contact properties according to customer requirements;

    ② Only the precious metal electrical contact materials are joined at the necessary positions of the electrical contact components, thus effectively saving precious metals and reducing components costs;

    ③ The formed composite material components which are continuously and automatically stamped from layered clad strips do not require riveting, welding or other processing. It not only simplifies the component manufacturing process and improves production efficiency, but also improves component contact position accuracy and bonding consistency.

4. Material advantages:

    ① Freely select precious metal alloy and coating thickness;

    ② The combination of shape, cladding thickness curve and material is suitable for application in the living example;

    ③ Combine multiple materials with superior bonding strength;

    ④ Due to the adjustability of the cross-section, ideal designs for connecting products and tools can be made;

    ⑤ Use the smallest amount of precious metals.

5. Application fields:

    ① General, communication, automotive relays;

    ② Micro, wall , thermostat switches;

    ③ Commutator, connector, regulator, fuse;

    ④ Products that realize automated production in the production and reliability requirements of various electronic components such as micromotor components and IC wire frames.
