What is core wire?
Tiefa Metallurgical Manufacturer said Core wire is a kind of alloy powder coiled by the band-shaped steel strip composite materials, mainly used in steelmaking and casting process, through the means of extra-oven refining for alloying and refining treatment.
This core wire is a metallurgical product, often referred to as cored wire or core wire, which consists of a metal core and a layer of steel strip wrapped around the outside in a basic structure. Depending on the alloy powder, cored wire can be categorized into calcium-silicon cored wire, calcium solid cored wire, carbon cored wire, and many other types.
We also can supply other alloy core wire as following.
