1. What is a brass coil/strip C28000?
A typical alloy material used extensively in manufacturing is brass. The common brass material C28000 brass coil is one of them, and we are interested in its strength and flexibility.
C28000 brass coil is a high-strength, highly corrosion-resistant brass alloy material containing approximately 70% copper and 30% zinc. This brass coil can be easily machined into a variety of shapes and exhibits excellent corrosion resistance in both air and water.
C28000 brass coil has high plasticity and can be processed into various shapes, such as pipes, wires, etc. At the same time, the strength of the C28000 brass coil is also higher, and its strength index is better than ordinary brass materials.
