Tantalum is ductile and highly resistant to acid corrosion. It has a high melting point and is a good heat and electricity conductor.
Tantalum is ductile and highly resistant to acid corrosion. It has a high melting point and is a good heat and electricity conductor. Niobium, also known as columbium, is frequently alloyed with Tantalum for applications requiring heat-resisting and combustion equipment.
Advanced Refractory Metals (ARM) provides consistently high-quality Tantalum Niobium Alloy products in a variety of forms, including tubes, rods, wires, etc. We’re capable of supplying custom materials.
