Operating from the heart of Addis Ababa, Tariku Metals takes pride in being a trusted supplier of specialized industrial materials. We are pleased to offer premium Beryllium Chromium Copper bars and rods, sourced to meet the exacting standards of Ethiopia’s growing manufacturing and technology sectors. Our commitment is to provide local engineers and fabricators with reliable access to these high-performance alloys, supporting innovation and quality in domestic production with both consistent supply and expert technical support.
The unique composition of this alloy combines copper with small but critical amounts of beryllium and chromium. This blend results in a material that achieves an excellent balance of very high strength and impressive hardness after a simple heat treatment. Despite this increased durability, it retains the outstanding thermal and electrical conductivity that copper is known for, making it a truly versatile engineering material for demanding applications.
