Choosing Metals for Your Project

Pick a metal by working backwards from the finished piece. What must it do, and what can your shop handle?

Knifemaking

• Simple high-carbon steels such as 1084 and 1080 harden well with basic equipment. A common first choice.
• 1095 and O1 reward more careful heat control with a fine edge.
• Stainless steels resist rust but usually need precise oven heat treatment. Many beginners send them out.
• Avoid unknown scrap at first. Old files and springs can work, but you’re guessing at the recipe.

Jewelry

• Copper: cheap, soft, great for practice. Tarnishes and can mark skin.
• Brass and bronze: gold-toned, harder than copper, good for pendants and cuffs.
• Sterling silver: 92.5% silver, stronger than pure silver, the standard for rings.
• Fine silver: pure, soft, tarnishes less, fuses without solder.

Small machining

• Free-machining brass: cuts like butter, gives clean chips.
• 6061 aluminium: light, common, easy on small machines.
• Leaded or free-cutting mild steel: cheap and predictable for practice parts.
• Stainless and tool steel: tougher on tools and machines. Learn on the easy stuff first.

Casting

• Lead-free pewter: low melting point, good first casting metal.
• Aluminium: needs a furnace, but scrap is plentiful.
• Bronze: beautiful, but much hotter and more demanding.

Before melting anything, read which metals to avoid melting. This is general guidance; follow the safety data from your supplier.
