Nickel-plated brass

Illustrated explanation

A coating, a metallurgical phase and a regulatory material unit

1Nickel-plated brass
A coating, a metallurgical phase and a regulatory material unitCallout 1: Plated brass section. Callout 2: Two metallurgical phases. Callout 3: Separate material layers. 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.

  1. Nickel-plated brassThis term

    The brass body and nickel surface finish have separate material characteristics. Confirm actual alloy, coating process and service evidence.

  2. Duplex stainless steel

    The stainless family has ferritic and austenitic phases. Composition and controlled processing determine the actual microstructure and properties.

  3. Homogeneous material

    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.
