CuSn8 Phosphor Bronze Strip is your good choice.Phosphorus is an effective deoxidizer for CuSn8 alloy. The addition of elemental phosphorus can improve the strength, hardness, upper limit of elasticity, elastic modulus and fatigue strength of CuSn8, and improve corrosion resistance and fluidity during casting. The disadvantage is to increase the anti-segregation of the ingot
C27200 CuZn37 Brass Strip is your good choice.The brass belt has good mechanical properties and wear resistance, and can be used to manufacture precision instruments, parts of ships, and shells of guns. Brass sounds good when knocked, so gongs, cymbals, bells, horns and other musical instruments are all made of brass. According to its chemical composition, brass is divided into two types: ordinary copper and special brass. (1) Ordinary brass is a binary alloy of copper and zinc.
Pure Silver Wire is your good choice.The transmission of copper wire to high, medium and low frequency is relatively uniform, but there are many common copper magazines, so it is not suitable to make audio signal transmission lines. Japan used oxygen-free copper OFC more than 20 years ago. Due to the reduction of impurities, the sound tends to be clear and transparent, but it is not good for low frequencies.
Silver Electrical Contacts are mainly used in contactors, switches, connectors, relays, and cross points in conductive circuits. Contact refers to the point of intersection where electronic appliances are disconnected and contacted when they are opened and closed.
The standard scale of rolled Pure Copper Foil is (0.05～0.010) mm (thickness) × (40～600) mm (width), and the length is generally not less than 5000mm when supplied in coils. The conditions are soft and hard, and most of them are hard. Its characteristics are: fine arrangement, uniform function; high surface finish, good public service; single minimum thickness and width are restricted. Rolled copper foil can be divided into oxygen-free copper foil for electron tubes, oxygen-free copper foil and red copper foil according to chemical composition, and corrosion-resistant alloy copper foil with trace elements and heat-resistant alloy copper foil are added.
Following my country's science and technology, many occupations have quickly carried out, especially the hardware profession, next we talk about the characteristics of beryllium copper:
