The challenge:
Purity that holds up under pressure
In medical, aerospace, and industrial systems, materials are pushed to the limit. There’s no room for variability. Any impurity or inconsistency can lead to failure, whether it’s in a thermal coating or an implantable device. These applications demand ultra-clean inputs with total reliability.
How we help:
Precision alumina for critical environments
TECHGuard™ delivers the high-purity alumina trusted in systems where performance, safety, and consistency are non-negotiable. With 4N-level purity and controlled formats, it supports dense, stable, and defect-resistant parts across spray coatings, ceramics, and structural applications. Available in powder with traceability built in.
Built for reliability. Backed by process control.
TECHGuard™ is manufactured using ISO9001:2015 certified processes for consistency, traceability, and performance. Whether used in sprayed coatings, pressure-resistant parts, or sintered components, it meets the demanding requirements of regulated and high-spec industries.
