MEDICAL PLATINUM CASTINGS
As the demand for medical platinum castings continues to rise, TechForm, with its robust background in serving this market, stands ready to meet the production standards required.
TechForm has its roots in serving the medical industry. Our first medical castings were orthopedic implants, and we later entered the field of endoscopic instrumentation. In 2005, after our company’s base metal division was sold, we focused on castings produced in platinum group metals.
Why Platinum for Medical Castings?
Platinum’s unique properties make it irreplaceable in a vast number of applications. These desirable properties will typically fall into one or more of the following categories:
- Density
- Biocompatibility
- Corrosion Resistance
- Electrical Conductivity
- High-Temperature Capability
Platinum 90% Iridium 10% for Medical Castings
This is a great all-around alloy that will not oxidize and has been widely used for years in both casting and fabrication.

Practical Properties
- Corrosion-resistant metal that will not oxidize
- Hypoallergenic metal—there are no documented cases of skin reaction
- Biocompatible metal—platinum is suitable for implant applications in humans
- High-density metal—platinum is one of the densest elements on earth, exceeded only by osmium and iridium, two other platinum group metals
- Unique metal—approximately 20% of goods manufactured in the world contain platinum or are produced using platinum due to its unique capabilities in terms of density, corrosion resistance, thermal conductivity, and catalytic abilities
- Platinum can be reclaimed from obsolete applications and sold at prevailing market prices for scrap
Medical Product Development
We are an experienced co-developer of products. Working in tandem with our medical customers, we ensure that cast products are developed as efficiently and effectively as possible. The prototyping process at TechForm is highly flexible using 3D pattern printing. This allows for simultaneous production of multiple design iterations if desired. Once a final design is determined through prototyping, hard wax or plastic injection tooling can be produced with minimal risk for the need for downstream modifications.
