Johnson Matthey (JM) is a world leader in platinum group metals (PGMs). For over 200 years, we have used advanced metals chemistry to tackle the planet’s biggest challenges.
Many leading energy, chemicals and automotive companies depend on our technology and expertise to decarbonise, reduce harmful emissions and improve their sustainability.
Our purpose, ‘Metals that matter, for a healthier world’, is rooted in our foundation, and alludes to the positive impact our solutions bring to people, communities and the environment.
PGMs are the metals that matter. From improving air quality and enabling clean energy and transport, to advancing cancer diagnostics, our products and services are helping to create a healthier and more resilient world.
And as the largest recycler of PGMs, we're embedding circularity at scale to help maintain a sustainable supply of these critical materials for the future.
Carpenter Technology develops and manufactures high-performance specialty alloys for aerospace, medical, defense, energy, and semiconductor applications where material failure is not an option.
Our customers operate in extreme environments — intense temperatures, pressure, corrosion, cyclic stress and regulatory constraints. From Kitty Hawk to Mars, we’ve partnered with innovators to push what’s possible: in the heat of an afterburner and the freezing void of space, from inside a heart to the bottom of the ocean, with nanometer precision and miles of scale.
We produce stainless steels, titanium alloys, superalloys, soft magnetic alloys, powder metals, and tool steels engineered to deliver strength, durability, and precision at scale. Products are precision-built to spec in-house, from premium melting and processing to finished bar, billet, wire, strip, plate, powder, and custom forms.
Our materials support:
Aerospace and aviation: High-strength, lightweight alloys for aircraft and spacecraft components operating under extreme thermal and mechanical stress
Medical: Ultra-clean alloys for implants and surgical systems designed to improve patient outcomes with fewer complications and faster recoveries
Energy: Materials engineered for traditional and additive manufacturing to push efficiency and potential in power generation systems
Semiconductor: High-purity alloys for corrosive, contamination-sensitive environments in advanced chip manufacturing
Defense: Next-generation metallurgy enabling stronger, lighter, and longer-lasting mission-critical equipment
With deep materials science expertise, vertically integrated manufacturing, and rigorous quality systems, Carpenter Technology helps customers reduce risk, improve performance, and meet demanding specifications.
