Estimate elemental ratios, total mass, impurity levels, and remaining fractions accurately. Switch input modes easily. Visualize alloy balance, percentage share, and component masses clearly.
Use consistent mass units across all rows. Grams, kilograms, or pounds all work if the same unit is kept.
| Component | Input Mass | Purity % | Atomic Weight | Comment |
|---|---|---|---|---|
| Copper | 70 | 99.9 | 63.546 | Main base metal |
| Zinc | 20 | 99.5 | 65.38 | Improves flow and hardness |
| Tin | 8 | 99.8 | 118.710 | Raises corrosion resistance |
| Nickel | 2 | 99.0 | 58.6934 | Small strengthening addition |

The calculator evaluates alloy composition on gross mass, pure mass, and mole basis.
Gross Total Mass = Σ component mass
Pure Mass of Component = component mass × (purity ÷ 100)
Impurity Mass = component mass − pure mass
Weight % = (component mass ÷ gross total mass) × 100
Pure Basis % = (pure mass ÷ total pure mass) × 100
Moles = pure mass ÷ atomic weight
Mole % = (component moles ÷ total moles) × 100
Scaled Mass = component mass × (target batch mass ÷ gross total mass)
These equations help compare blend balance, estimate purity losses, and resize a proven recipe for larger or smaller production runs.
It calculates total mass, component weight percentage, purity-adjusted mass, impurity mass, mole values, mole percentage, and scaled batch masses from your entered alloy recipe.
Yes. Any mass unit works if every component uses the same unit. The calculator keeps all ratios correct because it compares relative amounts.
Purity helps separate true metal content from impurity content. That gives a more realistic picture of effective alloy composition, especially in lab or recycled feedstock work.
Weight percentage uses mass share. Mole percentage uses particle amount based on atomic weight. Mole analysis is useful when chemistry behavior depends on atomic proportion.
No. Atomic weights are optional. They are only needed when you want moles and mole percentage. Weight-based calculations still work without them.
Gross total includes impurities. Pure total removes the impurity fraction using the purity input, so it represents actual metal content in the batch.
Yes. Enter a target final batch mass and the calculator returns scaled component masses, making recipe expansion or reduction much faster.
Yes. It works well for classroom examples, formulation checks, and preliminary production planning. Final industrial acceptance should still follow plant standards and lab verification.
