What is pewter alloy made from?
Generally, the pewter alloy is the result of a mixture of metals and the chemical specifications can vary. More specifically, when it comes to the metal proportions used to create the pewter alloy, in the case of European casting alloy this mixture contains approximately 94% tin, 5% antimony and the rest of 1% is copper. Likewise, in the case of Asian pewter alloy the mixture is creating based on the following chemical specifications: approximately 97.5% tin, 1.5% antimony and the rest of 1% is copper. This combination created a softer pewter alloy softer and it is used in Malaysia, Thailand and Singapore. While antimony, bismuth and copper are used to increase the hardness of the pewter alloy, lead is used for low grade pewter art pieces and it can reach even 80% lead.
