Semi-finished products
SAXONIA offers a wide range of semi-finished products. Our product portfolio ranges from individual melting products, tubes, rods, sheets and wires to anodes, targets, precision strips, milled and turned parts. Our high-quality semi-finished products are used as technical materials in many industrial sectors, or represent top-quality pre-materials for jewellery or investment goods. Depending on product, quality and customer requirements, for producing our semi-finished products we use both melting metallurgical processes – such as vacuum casting or continuous casting – and sintered materials.
