These brass disc blanks are purpose-made for makers, machinists, and repair technicians who need a reliable round metal starting point — whether you're fabricating custom gaskets, stamping jewelry, or shimming mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eEach disc is cut from solid brass (copper-zinc alloy, typically C260 or equivalent), finished to a uniform 1.5mm (approximately 0.059 in) thickness. Available diameters range from 20mm (approx. 0.79 in) to 150mm (approx. 5.91 in), covering the most common sizes needed for hobby metalwork, light industrial repair, and decorative fabrication. Edges are machine-cut and may require light deburring depending on your application.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include: cutting custom copper-alloy gaskets for plumbing fittings and valve seats, using brass disc blanks for metal stamping and jewelry blanks, and inserting round shim stock between mating surfaces in mechanical assemblies where precise spacing is required.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔧\u003c\/span\u003e\u003cstrong\u003eCompatible with:\u003c\/strong\u003e Hand tools, bench drills, laser cutters, CNC routers, metal stamps, and standard metalworking files.

Brass has excellent solderability with standard rosin-core soft solder (60\/40 or lead-free) and is compatible with silver brazing alloys.
