Al₂O₃
Alumina Ceramics
High-purity alumina for insulation, high-temperature containment and structural duty where strength and electrical isolation have to hold at the same time.
Material detailsFORM 03
Ceramic Rods
Solid rods and ground pins for structural, insulating and wear duty in tight assemblies.
Rods are the simplest ceramic form and the one where tolerance discipline shows most. Diameter and straightness are what make a rod fit a bore, hold a load or slide without binding.
Ground rod is specified when the rod has to mate with something else. As-fired rod is enough when it carries or insulates and nothing slides against it — and it costs less.

Made to your requirement
What is defined with you before production
- Diameter and its tolerance
- Straightness over the full length, not per unit length
- End geometry, and whether the ends are functional
- Any groove, step or thread, and where it sits
Supply stage
Sample part first, then batch production on the same material and process basis. Ask for the material data sheet with your quotation.
