Medical Grade Alloys
ASTM F75 Alloy
PML’s ASTM F75 ingots are precision-melted and tailored for additive manufacturing, investment casting, and high-performance component fabrication.
The Unyielding Blueprint for Modern Medical Solutions
A masterclass in medical-grade metallurgy, offering an impenetrable defense against wear and corrosion.
Ingot Manufacturing Process
High-purity ASTM F75 alloy ingots produced using advanced Vacuum Induction Melting (VIM) technology, ensuring metallurgical consistency and ultra-low impurity levels.
RFQ from Customer
Melting parameters and ingot requirements are defined based on customer specifications and end-use application.
Alloy Design/Planning
High-purity virgin metals are charged into the VIM furnace under atmosphere or vacuum, with alloy chemistry tailored through in-vacuum element additions.
Alloy Melting by VIM
Controlled vacuum melting with real-time spectrometry and oxygen analysis ensures consistent composition and microstructure.
Process & Quality Control
Melt is poured using a fully automatic vacuum tilting mechanism into customized metallic molds for defect-free ingot formation.
Primary Finishing
Post-solidification, the ingots are processed and finished per customer needs—ready for downstream use in powder, strip, or forged product manufacturing.
Testing & Packaging
Every ingot undergoes rigorous testing and inspection before secure packaging for dispatch.
