WO Mounting Plate
Today I took delivery of a magnificently machined William Optical Mounting plate. Once out of it's packaging it felt oddly heavy, far too heavy to be Aluminium.
I check on the WO website, and the plate was described as Anodised Aluminium. My son an undergraduate engineer immediately "poo-whoed" the suggestion that the plate was Aluminium, suggesting it is either stainless steel or machine steel.
Does the ultra-high grade Aluminium used by WO, weigh more than garden variety steel? Is there an alloy of Aluminium that weights more than standard Aluminum?
