Bimetal refers to an object that is composed of two separate metals joined together. instead of being a mixture of two or more metals, like alloys, bimetallic objects consist of layers of different metals. with a view to up-grade and achieve better stability in quality products, indotech bimetals has been given great efforts in the field of research and development in order to reach our goal. we have been continuing to acquire modern equipments to improve the manufacturing process of our bimetallic barrels by using en24, aisi4140. all the alloys which are used in these barrel blanks has been developed in indo tech bimetals ’s own material laboratory and continually tested under tough operating conditions.
