Metal casting
In reply to golf1982, Apr 21, 2013

I am not a metal casting expert but have engineered many products using cast/mold over my career.

Magnesium has some advantage over others

-low melting point.

- Almost no shrinkage during solidification.

- Good fill rate

These properties make it a material of choice for casting. In fact, my supplier can use the same LCD plastic mold to mold magnesium.

However, the molten magnesium is very fire hazardous. The mold must be done in vacuum or in inert gas environment. There are only a few molding house that can handle Mg molding.

Aluminum is higher strength than Magnesium but its moldability is limited, and can't hold tight dimension.

Titanium - no this stuff is more useful for something like jet engine instead. Titanium golf-club should be banned. Sorry.

A well engineered poly-carbonate with glass fiber and metal-structure backing will do just fine. Best engineered product is to make it functional and affordable for as many people as possible.

Stainless steel - good for making a stick to whack on the head of whoever is asking for.
