Good price and quality New energy connector components  are made of copper alloy materials with contacts for plugs and sockets. This is because copper alloy materials can improve the balance of strength, formability and conductivity of new energy connectors. New energy connector manufacturers mainly share the limited aspects of metallurgy of copper alloy materials for good price and quality New energy connector components  contacts!

First let's look at the alloy type, strengthening mechanism and conductivity. In terms of composition, the copper alloy used in good price and quality New energy connector components are mainly copper, with more than 70% to 99% of copper, and the rest is composed of a relatively small amount of alloying agent. The most common additives are tin (phosphor bronze), zinc (brass), and nickel (sometimes combined with tin, zinc, or cobalt). Special alloying agents, usually in small amounts, including beryllium (beryllium copper), silicon, cobalt, magnesium, iron and zirconium.

There are two basic types of copper alloys, which are solution hardening and precipitation / dispersion (P / D) hardening. Whether the alloy is solution hardened or P / D hardened depends on the amount of alloy added, and all alloys can also be work hardened.

Alloys containing tin and zinc are usually solution hardened alloys. Solution hardening is the result of several percentage to several percentage of alloying agent dissolved in the base copper. For example, phosphor bronze generally contains 4% to 8% tin. The most commonly used brass alloys include copper (70%) and zinc (30%), which retain the crystal structure of pure copper.

As mentioned earlier, all copper alloys are work hardenable, which means that when they are deformed or processed, their hardness and strength will increase. The strengthening mechanism is basically the generation of deformation and defects in the crystal copper lattice, which leads to the increase of resistance to further sliding and deformation. It should be noted that the work hardening characteristics vary with the alloy composition.

Good price and quality New energy connector components are usually made of strip materials. Processing large ingots into strips includes a series of rolling and annealing operations. Rolling hardens the strip and annealing softens it so that it can withstand additional rolling without cracking. The rolling / annealing procedure for producing new energy connector strips with a thickness from one millimeter to less than one tenth of a millimeter is proprietary to copper alloy strip manufacturers. For this reason, different good price and quality New energy connector suppliers may have different combinations of yield strength and ductility / formability for a given material strength level or tempering.

Next, consider phosphor bronze as an example of a solution strengthened alloy system. Since tin is doped into the basic copper lattice, it is instead in the position of the copper lattice, but there is a difference in the size between tin and copper atoms, which will lead to local deformation of the lattice. This deformation increases the resistance of the lattice to the sliding mechanism under applied stress, which actually enhances the material. Solution strengthening depends on the alloying agent and alloy composition. For example, the strengthening effect of each added percentage of tin in copper is higher than that of nickel or zinc. However, the incorporation rate of zinc and nickel can be higher than that of tin, while maintaining the lattice structure of copper.

The original International Annealed Copper Standard (IACS) copper standard was defined more than a century ago. Since then, copper processing technology has been improved. Therefore, the IACS conductivity of pure copper C11000 is now 101% (min) IACS instead of 100%. As a reference, some minimum IACS conductivity of copper alloy used in good price and quality New energy connector components are C26000 (brass) and 28%; 15% for c51000 (phosphor bronze); C17200 (be Cu) is 18%; 60% for C19400.

The conductivity of copper alloy contact materials for good price and quality New energy connector components largely depends on the amount of alloy added. Like solid solution strengthening, tin and nickel have a stronger impact on the conductivity than zinc. Other factors affecting the conductivity include grain size and work hardening, which have less impact than alloy additives.
