Magnesium Square Bar

Magnesium Forms

Magnesium Square Bar

Magnesium serves as an excellent example of engineering raw materials which are more difficult to source. Undoubtedly one of the primary reasons is due to cost - with a price which around 20% greater than the cost of aluminium alloys, magnesium represents a significant investment for any stockholder. Combine this with the fact that general use of magnesium in engineering is more niche, results in a raw material which historically more difficult to source.


While more difficult to source, magnesium is a popular raw material in high-technology applications. It possesses one of the best strength to weight ratios of any alloy, is considerably less dense than comparable alloys and has low resistance to cutting. However, care needs to be taken during processing due to the hazardous volatility of the alloy, especially if chips or dust come into contact with water.


Thankfully, we stock magnesium in a range of shapes and sizes, including magnesium square bar, which is available for supply on an ex-stock basis. We also provide you with processing services which ensures that you receive material from us cut to specific lengths. Regardless of whether you are looking for magnesium square bars or magnesium in other forms, we have the stock range, shapes and sizes to suit your engineering requirements.

We stock Magnesium Square Bar in a variety of grades.
