95% alumina generally identifies a ceramic with a nominal alumina content around that composition. For purchasing, the grade specification must establish how the content is stated and controlled. The label does not describe the entire formulation or guarantee a particular service rating.
Why grade identity still matters
Different materials can share the same nominal alumina percentage. Morgan’s official alumina range includes several distinct 95% grades, illustrating why the percentage alone is insufficient for substitution. Compare the actual grade data and intended use rather than treating every “95 alumina” part as identical.
Questions for a material quotation
- What grade and composition requirement will the quotation use?
- Which properties are relevant to the operating conditions?
- Are the published values typical data or agreed acceptance requirements?
- What material identification and inspection records are needed?
Keep the component requirements separate
A material description does not define the finished dimensions, surface condition or assembly fit. Attach the drawing, identify critical features and state temperature, electrical duty or contact conditions. If replacing an existing material, include its known grade and the reason for considering a change.
