Thermostat bimetal is composed of two or more metals or alloys with different expansion coefficients and has functional composites change in shape with temperature, wherein the alloy layer with larger expansion coefficient is called active layer, while the alloy layer with smaller expansion coefficient is called passive layer. An intermediate layer that plays the role of adjusting resistance can be added between the active layer and the passive layer. With its heating bending features, it can realize temperature indicator, temperature control, temperature compensation, overload protection, delay control and other functions.
It is a kind of clad metals taking low-carbon steel as the base material and formed by cladding with copper material in two or one side. It does not only have the high electrical and thermal conductivity of copper, but also have the high strength, high toughness and low cost features of steel. By adjusting the thickness ratio of copper layer, materials with various resistivities can be obtained, which is a good substitute for some coppers, brasses and other materials. Compared with iron plated copper material, this material has stable multilayer (copper layer) performance, and the thickness of the multilayer is uniform and controllable.
Vapor Chamber (VC) is a kind of new efficient heat dissipation product designed for integration, thinness and high performance in 5G field, and it can realize fast heat conduction and fast heat expansion functions.
Ultra-thin SS/Cu clad metals used for VC developed by the Company are compounded by 316L stainless steel and Cu in a layered solid phase with flat plate cut, consistent and steady physical property and precise and controllable thickness ratio relation. The thickness tolerance can be controlled at a micron order, which can be used for manufacturing of high-strength ultra-thin VC.
This material is mainly applied to new energy, electric power and other fields to solve the problem of connecting copper and aluminum materials. Compared with traditional friction welding, ultrasonic welding, laser welding and other means, it has a more reliable performance in bonding strength of materials.
Commonly known as fuse plate, the material made by side composite technology is horizontally spaced silver and copper. Copper is used instead of silver in the non-functional area to satisfy the role of electrical conduction, and silver is used as a melt in the functional area to save the number of precious metals. When the current is overloaded, the melt position (silver) is fusible, which can protect the circuit timely and effectively.
1. Silver-copper inlay clad metals
Silver-copper inlay clad metals are silvers or silver alloys inlaid in local position on the copper and copper alloy matrix and satisfy the purpose of saving previous metals under the premise of meeting performance requirements. It can be single-side inlay and front and back inlay; It can be single or multiple inlays, and its structural form can be adjusted according to specific demands.
2. Silver-copper overlay clad metals
Silver-copper overlay clad metals are materials that can be compounded to meet the welding performance requirements on the other side conditionally taking copper and copper alloy as the matrix and the silver or silver alloy corresponding to surface composite as the conductive contact layer. The other surface can composite materials that meet the welding performance requirements conditionally, such as iron, stainless steel, etc., and reach the purpose of saving precious metals and facilitating welding. Its structure form is generally two or three layers.
Special materials with excellent physical performance are taken as the working layer, and copper is taken as the base material to improve the overall strength and ductility of the material. It does not only reduce the amount of Ag and reduce the cost, but also has better performance.
