Hobbyists, prototype engineers, and research labs working with weight-sensitive assemblies need sheet material that is dimensionally consistent, easy to machine, and available in small quantities — without committing to industrial minimums.\u003c\/p\u003e\n\u003cp\u003eThese AZ31B magnesium alloy thin sheet plates are cut from wrought AZ31B-H24 alloy stock — a commercially standard magnesium-aluminum-zinc composition. Each plate is available in thicknesses of 1.0 mm (~0.039 in), 2.0 mm (~0.079 in), and 3.0 mm (~0.118 in), with planar dimensions ranging from 100×100 mm (~3.94×3.94 in) to 200×200 mm (~7.87×7.87 in). Surface finish is mill-rolled with a consistent flat profile.\u003c\/p\u003e\n\u003cp\u003eTypical applications include lightweight structural brackets for UAV and RC aircraft frames, sacrificial anode blanks for cathodic protection research, biomedical implant prototyping where low density and biocompatibility are required, and thermal management substrates in electronics R\u0026amp;D. The AZ31B alloy sheet plate is also widely used for CNC milling practice and educational metalworking projects where machinability and low cutting resistance matter.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Suitable for CNC milling, laser cutting, EDM, and conventional machining.

The 1.0 mm sheet offers the lowest weight for non-structural skins, while 2.0 mm is preferred for motor mounts and structural ribs. Order a 2-piece pack of the 1.0 mm variant to allow for test cuts before committing to your final design.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan these plates be used as sacrificial anodes for corrosion protection research?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes.
