1. Introduction to metal shrapnel
Metal shrapnel, also known as metal shrapnel, belongs to the category of hardware stamping parts and electronic hardware materials. The common precision hardware spring is an important metal part of electronic components, which usually plays the role of conduction, switch, clamping, resonance, etc. Most of the shapes are S type, C type, N type, round, Z type, spoon type, etc.
2. Production process of metal shrapnel
The production process of metal shrapnel is a special process of processing materials into parts through cold stamping of stamping dies.
3. Application range of metal shrapnel
Metal shrapnel is mainly used in mobile phone cards, mobile phone antennas, membrane switches, contact switches, PCB boards, FPC boards, medical devices, headphone audio sockets, connectors, micromotors, sensors, relay switches, digital 3C, automotive instrument touch switches and other products.
4. Common materials of metal shrapnel
Commonly used: beryllium copper (requiring heat treatment), titanium copper, phosphor bronze, brass, stainless steel, spring steel, etc.
5. Surface treatment requirements for metal shrapnel
Gold plating, silver plating, nickel plating, tin plating, oil stain ultrasonic cleaning, etc.
