Frankenrazor

[Rwoodreno]

Per a Google search Zamak is about 80 to 85% of the weight of steel so is going to be over twice the weight of an aluminum razor handle. 6.6 grams/cubic cm while steel is 7.5 to 8 g/ccm depending on the alloy type.

I also have the Rockwell 6S and 6C series razors, being a supporter of the 6C Kickstarter project. The 6C is all Zinc alloy and weighs 3.45 ounces while the identical appearance and dimensions stainless steel 6S weighs 4.15 ounces. The zinc alloy that Rockwell uses is 83% as dense as the stainless steel based on these weights and neither can be called a light weight razor even by modern standards. Both are lighter per cubic cm than most brass and bronze alloys.
