Product Description

singwei's pure tin strips have a range of outstanding features for a wide range of high quality welding and tinning processes, especially for soldering copper additives and wire and cable tinning processes:

The first high tin content: The purity of the pure tin strip reaches more than 99.9%, ensuring that the high purity requirements in the welding and tin plating process are met.

The second high purity fine tin material: The use of high purity fine tin smelting, eliminating the existence of impurities and impure substances, providing excellent purity and quality.

Third, less tin residue: Due to high-quality raw materials and fine preparation, pure tin strips have a lower tin residue content, which helps to reduce impurities and pollution in the production process.

Fourth, small surface tension: the surface tension of the pure tin strip is small, making it easier to wet the solder joint or the surface of the workpiece in the welding and tinning process, ensuring good wettability.

Fifth, good wettability: Excellent wettability ensures that the tin metal can be evenly coated on the welding surface or workpiece to form a solid solder joint or tin layer.

Sixth, wide application: pure tin is suitable for a variety of welding processes, especially wave soldering copper additives and wire and cable tinning process, to meet the needs of a variety of high-quality applications.
