Annealing C21000 Brass Sheet

C21000 brass consists mainly of copper and zinc, of which the copper content is about 60% to 70% and the zinc content is about 30% to 40%. It may also contain small amounts of lead, tin and aluminum to enhance its mechanical properties and corrosion resistance. The composition ratio of this alloy gives it good physical and mechanical properties.

Product Introduction

Henan Gnee New Material Co., Ltd. is one of the most professional manufacturers and suppliers of annealing c21000 brass sheet in China, specialized in providing high quality copper products with competitive price. Welcome to buy discount annealing c21000 brass sheet for sale here from our factory. Customized orders are welcome.

 

C21000 Annealed Brass Sheet is a high quality copper alloy material that is annealed to improve its physical and mechanical properties. Annealing is the process of heating a material to a certain temperature and then controlling the cooling rate so that it cools slowly, with the aim of removing internal stresses, improving plasticity and toughness, and homogenizing grain size.
