Medals can be made of metal, pvc, crystal, acrylic, wood,etc.. But here I would like to talk about the common metal maerials used when making medals and listed their characters as below for your reference.
Zinc Alloy: Great 3D effect.
Pewter: Great 3D effect. Details can be performed better.
Copper/ Bronze: Looks high class. More often used in military products.
Aluminium: Light and soft.
