Welcome to Maduka Metals, your trusted partner for premium industrial materials right here in Abuja. We take pride in supplying top-quality Copper C10940 bars and rods, sourced to meet the rigorous demands of Nigeria’s growing industries. Our commitment is to provide not just a product, but a reliable solution backed by local expertise and a dedication to supporting the projects that are building our nation. When you need strength and conductivity you can count on, we are here to deliver.
Copper C10940 is essentially pure copper, containing a minimum of 99.90% copper, which gives it its exceptional characteristics. This high purity is what allows for outstanding electrical and thermal conductivity, making it a top choice for demanding applications. The material is also known for its excellent formability and ductility, meaning it can be easily shaped and bent without losing its integrity. It’s a soft yet tough metal that offers good corrosion resistance, combining practical workability with long-lasting performance.
