A coating, a metallurgical phase and a regulatory material unit
- Nickel-plated brass
The brass body and nickel surface finish have separate material characteristics. Confirm actual alloy, coating process and service evidence.
- Duplex stainless steel
The stainless family has ferritic and austenitic phases. Composition and controlled processing determine the actual microstructure and properties.
- Homogeneous materialThis term
The applicable RoHS definition determines the material unit assessed. A coated assembly is not automatically one homogeneous material for substance assessment.
Nickel-plated brass has a distinct surface layer over its brass body. Duplex stainless has two metallurgical phases; a homogeneous-material assessment instead concerns the applicable material separation definition.
Conceptual material sections, not composition or phase-fraction measurements. A layer or phase shown here does not establish corrosion, coating quality or regulatory conformity.
