Chemical and functional materials
Conductive Materials
From next-generation energy to advanced semiconductors, we expand the value of core materials.
LT Metal’s bonding material technology enhances the reliability of power semiconductors
Ag particles for power semiconductor bonding are a key material that sinter-bonds the chip to the substrate, ensuring device performance and reliability.
Based on its precious metal and fine-particle manufacturing technologies, LT Metal develops and produces low-temperature sintering Ag particles with high thermal conductivity and excellent heat-resistance reliability.
We optimize Ag particle size, shape, size distribution, and surface properties to suit each customer’s package structure and bonding process, delivering high-performance bonding materials.
LT Metal’s composite material technology completes the performance of next-generation batteries
Ag-C Layer material for all-solid-state batteries is a key material that induces uniform lithium deposition and migration at the anode–solid electrolyte interface, improving battery performance and service life.
Based on its precious metal and composite material manufacturing technologies, LT Metal develops and produces high-performance Ag-C Layer materials specialized in reducing interfacial resistance and suppressing dendrite formation.
We optimize Ag particle size, content, dispersion, and composite structure to match each customer’s all-solid-state battery design and performance requirements, delivering high-quality battery materials.

Why LT Metal
Three Design Capabilities
Global customers choose LT Metal because our design capabilities in structure, surface, and reliability allow us to deliver the performance and quality they require. This is LT Metal’s core competitive strength.
We Design Structure
We design the particle size distribution and morphology (spherical, flake, irregular) of silver powder and the active coating structure of DSA for each application. We produce major precious metal chemical materials in-house, including plating solutions, powders, and DSA electrodes.
We Design Surfaces
We precisely control the surface of conductive materials to achieve the optimal properties our customers require. By custom-designing coating agents and ligands for each process and material, we provide surface treatment solutions that maximize dispersibility and functionality.
We Design Reliability
We offer a material lineup that complies with global environmental regulations such as RoHS and REACH. Our precious metal recovery service for used conductive materials helps customers achieve their ESG goals (supply of UL-certified products) while reducing costs.
