Brass Plate Weight Calculator
Calculate the weight of Brass Plate by entering your dimensions. The density of Brass is 0.3065 lb/in³ (8484 kg/m³). Use this calculator for quick stock weight estimates in your CNC machining projects. Accurate weight calculations are essential for shipping quotes, material cost estimation, fixturing load analysis, and structural design verification. The theoretical weight formula assumes a uniform cross-section and standard alloy density; actual weights may differ slightly by grade and mill tolerance. Weight data is calculated using the standard volumetric formula multiplied by the material density constant shown above.

Sourcing and Use Notes
C360 free-cutting brass (61.5% Cu, 35.5% Zn, 3% Pb) is the default machining brass — runs at high SFM with sharp positive-rake tooling and produces small broken chips ideal for Swiss-style turning. Used for plumbing fittings, decorative hardware, gears, and electrical connectors where solderability and dimensional stability matter. Lead-free brasses such as C314 and C485 are increasingly required for drinking-water and food-contact parts under NSF/ANSI 372; expect slightly poorer chip control and lower achievable surface speeds versus C360.
Plate stock is the foundation for machine bases, structural gussets, weldments, waterjet and laser blanks, fixture base plates, and adapter brackets. Cold-rolled plate offers a clean descaled surface acceptable for paint or anodize directly; hot-rolled plate carries mill scale that must be ground or sandblasted off before coatings. Standard thicknesses jump in coarse steps (3, 5, 6, 8, 10, 12 mm; 1/8, 3/16, 1/4, 3/8, 1/2 inch) so design around the available stock rather than specifying an odd thickness that triggers cut-down charges and longer lead times.
Common Applications
Brass Plate is a standard stock form used in structural frames, machine bases, brackets, and fabricated components. Its consistent cross-section simplifies weight-per-foot calculations and material takeoffs for procurement and shipping cost estimates. Engineers and machinists rely on theoretical weight data during the quoting and planning stages before final parts are produced. For large orders or weight-critical designs, request certified mill test reports (MTRs) to confirm actual density and alloy composition.
Sourcing and Weight Tolerance Note
This weight is based on the theoretical density of Brass. Mill tolerances (ASTM A6 allows ±2.5% on cross-sectional area for structural shapes) and surface treatments (anodizing, plating, painting) may add 1–3% to actual shipped weight. Order 5–10% material overage to account for saw kerfs and offcuts. Always verify actual material density with your supplier's material test report (MTR) for critical structural or load-bearing applications. Compare weights across materials using the comparison table above to make informed material selection decisions for your project.
