Product Introduction
Indium tin alloy wire is an alloy wire composed of indium (In) and tin (Sn). Steel with an In content of 4%~90% can be configured for production. Common ratios include Sn80ln20, Sn50In50, and Sn4ln96. This type of indium tin wire has a wide range of applications and is often used in semiconductor, automotive, aviation, low-temperature solder, ITO target materials, low melting point alloys, as well as bearing alloys, sacrificial anode materials, batteries, and other fields.
This solder wire is Sn4% In96%, which has the characteristics of low melting point, low residue, good wetting, strong fluidity, and fast soldering. This solder wire is Sn4% In96%, which has the characteristics of low melting point, low residue, good wetting, strong fluidity, and fast soldering.
4. High oxidation resistance: The addition of indium improves the corrosion resistance and oxidation resistance of the alloy, extending the service life of the solder joints.
This lead-free welding wire has a low melting point and good fluidity, making it suitable for general electronic welding. It is commonly used in situations where a low melting point is required but still requires a certain mechanical strength. Moreover, the product has good performance and strong oxidation resistance. During the production process, it can effectively suppress the growth of interface metal compounds and improve the weldability of solder joints.
The high indium content makes the alloy more flexible, which is beneficial for handling small or complex welding tasks. This product adds convenience to the customer's production process and is very suitable for meeting the rapid development needs of modern electronics industry and welding technology.
After years of practice and application, it not only meets high standards of quality and performance. And it meets the needs of contemporary industries while maintaining environmental responsibility.
