Product Details
Product Introduction
Pure Tantalum Rod has special properties such as low thermal expansion and good thermal conductivity, sufficient resistance to electrical resistance, high modulus of elasticity. Therefore, the product is widely used in various fields such as support line, lead-in line, printer needle, various electrodes and quartz furnace, filament, high speed tools, auto auto products and sputtering target. The Pure Tantalum Rod also has excellent chemical properties and extremely high corrosion resistance. The product has no effect on chlorine gas bromide dilute sulfuric acid and many other agents in alkali solution, but only reacts with hydrofluoric acid and hot concentrated sulfuric acid.
Features
Our Pure Tantalum Rod could replace the tasks previously undertaken by precious metal platinum, thus greatly reducing the cost. Tantalum also plays an important role in modern medicine. It has been shown not to cause any damage, but also to cause the body's muscles to grow on it, medically known as biocompatibility. Tantalum's properties are used by doctors to repair and seal cracks and defects in broken skulls and limbs.
