TIMETAL® 54M for Improved Producibility and Machinability
TIMETAL® 54M is an alpha-beta titanium alloy that provides a producibility benefit over Ti-6-4 for parts requiring extensive machining. Trials have shown a 30% improvement in machinability, a 32% improvement in tool life at high machining speeds, and less damage to the tool inserts for the machining mill annealed grade. TIMETAL 54M also exhibits superplastic forming (SPF) capability.
TIMET has produced more than 250 metric tons of TIMETAL 54M to date using EBSM and VAR processes. TIMETAL 54M is already used in automotive turbochargers. TIMET is currently in the process of obtaining an AMS specification aimed at facilitating Commercial Aerospace applications. The tensile and toughness properties of TIMETAL 54M satisfy typical Ti-6-4 specification requirements. TIMETAL 54M is manufactured using “green technology” that can revolutionize the production efficiency of titanium components for industrial and commercial applications.
TIMETAL® 18: High-Strength Forging Alloy for Structural Airframe Applications
TIMETAL® 18 is a new near-beta alloy developed by TIMET to provide incremental property improvements over current high-strength titanium alloys (e.g., Ti-10-2-3 and Ti-5-5-5-3) for large structural forgings where deep hardening is required. Used in landing gear, this high-strength titanium alloy is lighter and offers lower maintenance than conventional steel components. TIMETAL 18 offers superior strength-ductility combinations and optimal hardenability while avoiding harmful segregation.
TIMETAL® PGMA: High-Grade Titanium Performance at Common-Grade Titanium Prices
TIMETAL® PGMA (platinum group metal appliqué or "patch") technology extends pure titanium corrosion resistance to levels that compete with high-cost palladium-containing grades. PGMA provides, even in the harshest applications, grade 7 like corrosion resistance, yet at a fraction of the palladium cost. That is great news for challenging corrosive applications like nickel recovery, bromine chemical production, reducing acids and other oxygen-deprived environments.
TIMET began developing the innovative technology 10 years ago, discovering that adding a small PGM alloy appliqué by fusion or resistance welding on a titanium substrate provides high-grade protection against pitting, stress fractures, hydrogen-induced corrosion fatigue, and general acid attack. Today, PGMA is solving serious corrosion challenges in the extreme heat of Australia and in the sandy deserts of the Kingdom of Jordan.
TIMETAL® Exhaust XT for Automotive Exhaust Applications
TIMETAL® Exhaust XT is a highly formable titanium alloy designed specifically for automotive exhaust sheet and tube materials. Compared with CP Ti Grade 2, TIMETAL Exhaust XT demonstrates improved oxidation resistance, higher strength and reduced deterioration after exposure at elevated temperatures, yet with similar forming and welding characteristics. This product answers the growing demand for titanium for exhaust applications due to its enhanced performance, ability to improve fuel economy through weight reduction and superior appearance.
Used today in:
- Exhaust pipes and mufflers for high-performance motorcycles
- Original equipment on select Porsche models
- Aftermarket exhaust systems designed for BMW M Series, Mercedes AMG and other high-performance brands
