MATERIAL SCIENCE OVERVIEW
From composition to performance.
Jewellery alloy behaviour is created by the relationship between elemental balance, microstructure and manufacturing history—not by karat alone.

SYSTEM
A connected material system
Every change upstream affects the bench. We connect four layers so colour, hardness and workability are engineered as one production system.
- Composition
- Microstructure
- Properties
- Production
PERFORMANCE
Three performance domains
The alloy is evaluated through the properties that matter during jewellery production and in the finished piece.
Hardness engineering
Balance strengthening elements and thermal history to reach a useful Vickers hardness without creating brittle behaviour.
HV · STRENGTH
Colour control
Control the relative balance of gold, silver, copper and whitening elements to maintain a repeatable signature tone.
L*a*b* · TONE
Workability
Manage grain structure and ductility for casting, rolling, stamping, turning and diamond cutting.
FLOW · FORMCONTROL
Variables we control
A practical formulation is built by matching material variables to the intended process route.

Final performance depends on the complete alloy grade and production conditions. Laboratory values and production trials should be interpreted together.
