3 Magnesium alloy cast slab/billet

Magnesium alloy cast slab is used to make magnesium tooling plate or feed to the magnesium slab

extrusion or magnesium slab rolling mill to get magnesium sheet. Magnesium cast billet is a

feedstock for forging magnesium parts.

We use the wrought magnesium alloy LFEC tech to cast the wrought magnesium alloy slab/billet

in semi-continuous casting process. The wrought magnesium alloy has fine surface and inner

evenly alloying element distribution, no air vent and dendrite, etc.

We can supply in customised cut sizes on request or via our standard size range. Billet/slab is with

a fully machined surface. More detail information, please see our Products Sheet.
