Diamond Tinning Dies Tin Coated Dies for Copper Wire
Diamond tinning dies are specially used for copper wire tinning and drawing and adjust the thickness of plating of tin-plated copper wire. Using titanium alloy as the case, it can float in tin water due to the titanium alloy is light than tin, so that minimizes adhesion of tin to the case. Tinning dies have the advantages of not sticking tin and blocking holes, and improving the uniform coating thickness and geat surface quality of tin-plated copper wire. And Standard case size φ25x7 mm.
Types:
Natural diamond tinning dies; (0.01-0.5mm)
Single crystal diamond tinning dies; (0.01-0.5mm)
PCD tinning dies. (0.1-3mm)
Product Features:
High precision;
Uniform coating thickness and quality;
Excellent coating surface finish;
Corrosion resistance;
Long working life.
Notes:
1. The main purpose of tinning the copper wire is to prevent copper from being oxidized when exposed to the air to form a film - patina (chemical formula CU2(OH)2CO3). The patina, on the other hand, is poorly conductive and increases resistance. Tin-plated copper wire can prevent redox reaction and produce patina; can increase heat dissipation; can improve electrical conductivity and improve wire performance. .
2. In addition, the tinning of the copper wire can also prevent the insulating rubber from sticking, the wire core becomes black and brittle, and improves its solderability. Tinned copper wire is mainly used for rubber-insulated mining cables, flexible wires, flexible cables and marine cables, etc. as conductive cores, and as outer shield braid and brush wire of cables.
