Firmetal Co., Ltd. products

To make a rod & bar first we need to forge or extrude the material to suitable size. The representative sections’ yield is 70%~90%. Then we anneal the material. Forging, rolling, extruding and drawing are usually used during reprocessing. The wire need to be forged by regular wire drawing machine.

Electron beam melting tantalum ingot - at room temperature (400 °C or less) forging breakdown - annealing - roughing - annealing - strip rolling - annealing - foil rolling - heat treatment. Cold rolling is usually applied, the total machining rate is 80% to 90% of the thickness of the slab, and the total processing rate is 6% to 8% of the plate thickness. In order to ensure the surface quality of rolled sheet, it is required to have no defect, pollution and roll surface.

Tantalum powder as raw material is processed into tantalum wire through rolling, drawing and other plastic processing working. The majority of tantalum wire is used in tantalum electrolysis and anode connection in the field of electronic industries.

Ta can be made into welded tube and seamless tube which are all widely used in industry. Seamless tube is made by extruding, hole shrinkage or plate deep drawing. Welded tube is made by forming a strip first, then shape it into tube, finally weld the seam with GTAW. We produce pure tantalum tube, 90%Tantalum 10%Tungsten, 97.5%Tantalum 2.5%Tungsten, 60%Tantalum 40%Niobium tube in different dimensions to meet customers` request.

Niobium and niobium alloy rod & bar are widely used in chemistry, electronics, aerospace and other fields due to its high melting point, corrosion resistance and cold processing properties. Rod surface allows a depth of less than half of the diameter tolerance. Pits, abrasions, scratches, and allows for straight, straight spirals and slight forged marks.

Our pure zirconium UNS R60001 and zirconium alloy rod & bar products all follow ASTM B-351, ASTM B-352 (Nuclear application) and ASTM B-551 (Non-nuclear application). Such as Zr702 (R60702), Zr705 (R60705), Zr-2 (UNS R60802), Zr-4 (UNS R60804), Zr-2.5Nb (UNS R60901, UNS R60904), Zr-1Nb rod & bar and other alloys` bar.
