Whether you're a hobbyist building a custom bracket, a small-shop machinist cutting blanks, or a maker reinforcing a structural assembly, these 10mm thick aluminum alloy plates give you a ready-to-use starting point without the waste of oversized stock.\u003c\/p\u003e\n\u003cp\u003eEach plate is cut from aluminum alloy flat bar stock, 10mm (approximately 0.39 in) thick. Available widths and lengths range from 100×100mm (~3.94×3.94 in) up to 150×200mm (~5.91×7.87 in), with multiple size options in between. Sold individually or in multi-piece packs of 2, 3, or 5 for projects requiring matched blanks.\u003c\/p\u003e\n\u003cp\u003eTypical applications include custom mounting plates for electronics enclosures, spacer blocks in mechanical assemblies, flat stock for CNC routing or manual milling, and structural gussets in lightweight aluminum alloy fabrication projects. The consistent 10mm thickness makes these plates well-suited for tapping threads, countersinking fasteners, or stacking as precision shims.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n\u003cstrong\u003eCompatibility Note:\u003c\/strong\u003e These plates are uncoated aluminum alloy flat stock.
