Product Introduction
Cast copper ingots refer to copper blocks formed by injecting purified copper liquid into a pre-made mold and cooling and solidifying it. This type of copper ingot can be widely used in the production of wires and cables, mechanical parts, architectural decorations, and various copper alloy products as raw materials for subsequent processing.
Product Features
High Purity
Our cast copper ingots use high-purity electrolytic copper with a purity of more than 99.95% as raw material. This material has extremely low impurity content and can increase the conductivity of the finished copper parts to more than 58 MS/m (the international standard is 57 MS/m).
Smooth Surface
The cast copper ingots use graphite molds with high thermal conductivity, so that the copper liquid cools quickly after contacting the mold surface, forming a hard solid layer, preventing bubbles and impurities from floating to the surface, so that its surface roughness Ra≤3.2μm, reducing the need for surface treatment in subsequent processing.
Consistent Block Weight
The weight of each copper ingot is controlled within the range of 15±0.2kg, which is much smaller than the international standard ±0.5kg. The small difference in the weight of copper ingots means that the automated handling equipment does not need to frequently adjust the strength of the clamp during handling, and can quickly grab each copper ingot.
