Chemical and functional materials
Chemical and functional materials
The design of one micrometer of surface determines a product's life and performance.
LT Metal precious-metal chemistry engineers that surface.
Precious-metal chemical materials are functional materials for electrolytic plating, electroless plating, ink and paste coating, and electrochemical processes. They bring the electrochemical properties, corrosion resistance, reliability, and catalytic activity of precious metals to the surface, improving the performance and service life of our customers’ products.
Plating material application guide
Which plating material do you need?
The right plating material depends on the service environment (current, temperature, chemical exposure), required thickness, substrate material, and environmental regulations.
Decorative and consumer goods Rh, Ag High gloss, oxidation resistance
| Application | Suitable precious-metal plating | Why it is selected |
|---|---|---|
| Semiconductor WLP (wafer-level packaging) | Au, Ni, Cu, Sn, Sn/Ag | Reliability, protection against oxidation and corrosion, high electrical conductivity, and low contact resistance |
| Printed circuit board (PCB) final finish | Au, Ag, Ni, Cu | Solderability and contact |
| Selective plating for connectors and contacts | Au, Ag, Pt, Pt, Ru, Ni, Cu | Wear resistance, corrosion protection, low contact resistance |
| Medical and implant components | Pt, Rh | Biocompatibility and corrosion resistance |
A full range of silver powder products
Silver powder
The electrical conductivity, dispersion, and sintered density of silver powder change sharply with particle morphology. Designing and selecting the right morphology for the application governs final product performance.
| Morphology | Conductivity | Dispersion | Characteristics | Primary applications |
|---|---|---|---|---|
| Spherical | Low | High | Dispersion in paste is the priority | Conductive inks and inkjet printing; high-temperature sintering for chips and solar cells |
| Flake | High | Medium | Layered alignment maximizes conductivity | Electrode pastes, EMI shielding |
| Irregular | Medium | Medium | Cost-efficient, general purpose | Sintered electrodes, general-purpose pastes |
A core material for the electrochemical industry
Insoluble anodes (DSA)
A dimensionally stable anode (DSA) is a titanium substrate coated with precious-metal oxides (RuO₂, IrO₂), giving durability and efficiency in electrolytic and electrochemical processes. Demand is rising across the electrochemical industry: chlor-alkali, water treatment, electrolytic plating, and green hydrogen water electrolysis. LT Metal controls the composition and thickness of the active coating precisely, delivering optimal performance under your electrolysis conditions of current density, electrolyte, and temperature.

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.
The chemistry, pH, current density, and temperature of the plating bath determine deposit quality. As a manufacturer of precious-metal chemical materials, LT Metal understands how material properties and process conditions interact, and engineers the chemistry to fit your plating process.
We engineer structure.
We engineer the particle size distribution and morphology of silver powder — spherical, flake, irregular — and the active coating structure of DSA to suit the application. Plating solutions, powders, and DSA electrodes: our principal precious-metal chemical materials are produced in-house.
We engineer reliability.
We maintain a material lineup that meets global environmental regulations including RoHS and REACH. Our precious-metal recovery service for spent plating solutions supports your ESG targets — including the supply of UL-certified products — and lowers cost at the same time.
