Automotive & Mobility
Stable operation of automotive and EV electrical components begins with reliable contact technology.
Market trends
The EV transition is redrawing the automotive materials landscape
As the global EV market grows, the automotive industry is electrifying fast. Electric vehicles use more electrical and electronic control components and more semiconductors than internal combustion vehicles, and the vehicle electrical/electronic (E/E) systems that govern performance and safety are becoming more important.
The shift from 400V to 800V high-voltage systems, the growth of autonomous driving sensors, and the expansion of in-vehicle communication modules are creating new demands on automotive materials. With their high reliability and durability, precious metal materials are critical to the core components of future mobility.

Why LT Metal
Three engineering capabilities
Global customers choose LT Metal because our engineering capability in composition, structure, and reliability delivers the performance and quality they specify. That is our core strength.
We engineer composition.
We develop alloy compositions for automotive precious metal materials with EV high-voltage conditions and your start-of-production (SOP) timeline in view. From contact materials to FCEV catalyst materials, we design solutions with you that match your stage of electrification.
We engineer structure.
We optimize the microstructure of automotive contact, plating, and catalyst materials for your process conditions and required performance. Our engineering support runs continuously from small-lot prototyping to volume supply.
We engineer reliability.
We operate a quality management system certified to IATF 16949 and meet the strict quality standards of global OEMs and Tier 1 customers. We support a structured quality verification process from material approval through volume application.
