Brass Coil
Brass Coil
Mittal Engineering is one of the leading Brass Coils Manufacturer & Supplier in Nepal. we are engaged in supplying and exporting the finest quality brass coils. Though the brass is an alloy of copper and zinc that basically consists of about 67% copper and 33% of zinc, this ratio can be modified to produce different brasses.
Mittal Engineering Industries delivers the brass with a unique set of physical properties such as dynamic, durable, and distinctive and are good enough to be used in the manufacturing of a great assortment of applications and products. It has good thermal properties such as conductivity, malleability, corrosion resistance, fatigue resistance, and high tensile strength making it the perfect metal for making electrical components including electrical sockets and plugs and several other technical instruments.
At Mittal Engineering Industries, we can create world-class products which have a brilliant surface finish, are dimensionally accurate, and subject to ready to work for any kind of application. We are flexible with skilled technicians as well as high-tech equipment allows us to cast different sizes, designs, and finish products in order to meet the customer’s specifications attentively.
