Fuelling Scientific Discovery and Industrial Innovation

Testbourne Ltd is a trusted name in the supply of high-purity materials, sputtering targets and scientific instrumentation for the research and advanced manufacturing sectors. For over 45 years, we have helped companies, institutions and researchers worldwide unlock new possibilities in science and technology by providing materials with uncompromising quality and performance.

Our history is built on reliability, technical know-how and a deep understanding of the industries we serve. Whether it’s supplying materials for thin-film deposition in semiconductor fabrication, precision components for optics and photonics or sourcing rare and custom materials for R&D, our commitment remains the same: to support progress through precision.

With thousands of materials available in various forms - foils, wires, powders, rods, discs and more, we are uniquely positioned to support both one-off research needs and large-scale production requirements. Every material we supply is backed by traceable documentation, rigorous analysis and expert support from our in-house team.

Who We Work With: Supporting Innovation Across Sectors

At Testbourne, we serve an incredibly diverse range of clients, from world-renowned research universities and government laboratories to advanced manufacturers, OEMs and innovative start-ups. What ties them all together? A demand for exceptional material purity, consistent performance and expert technical guidance, so that’s exactly what we deliver.

In academia and R&D, our materials fuel pioneering work in fields like quantum physics, nanotechnology, surface science and thin-film engineering. We provide bespoke, small-quantity supplies tailored to experimental needs and our in-depth technical knowledge ensures researchers select the ideal material forms, bonding methods or purity grades for their projects.

Across the private sector, we support a broad spectrum of industries, including:

• Semiconductors and Electronics: Delivering advanced materials for PVD processes, micro-resistors, capacitor production and semiconductor research and manufacturing.
• Solar and Renewable Energy: Supplying sputtering targets, sensors and thin-film materials for solar cells and photovoltaic technologies.
• Medical and Clinical Diagnostics: Providing instruments, reagents, consumables and single crystals essential for accurate diagnostics, research and medical‑imaging applications.
• Optics: Offering premium evaporation materials and PVD components used for IR coatings, anti-reflective layers, beam splitters and precision optical applications.
• Architectural, Automotive and Glass Coatings: Supplying sputtering targets and advanced coating materials for architectural, automotive, photovoltaic and mirror‑glass applications.
• Hard‑Wearing and Decorative Coatings: Delivering high-performance coatings for tooling, industrial use and stylish finishes in consumer products like watches, mobile devices and appliances.
• Ultra‑High Vacuum (UHV) and Vacuum Technology: Providing vacuum components, including Ceramaseal® feedthroughs, essential for synchrotrons, spectroscopy, semiconductor fabs, nuclear physics, MRI systems and other demanding environments.

What We Supply: Products Designed for Precision

Our product portfolio is built to support applications where purity, performance and precision are essential. We stock and supply a wide range of high-purity elements and compounds, many of which are available in multiple physical forms, such as:

• Foils: thin, ductile sheets for electrical, optical or chemical applications
• Wires: available in standard and ultra-fine diameters for precision bonding or sensor work
• Powders: including spherical and irregular grains for sintering, coating or additive manufacturing
• Rods: used in evaporation and vacuum deposition systems

We also specialise in sputtering targets, which are essential for producing high-performance thin films. Our range includes both elemental and compound targets, available in planar and rotatable formats. We support target bonding to a wide variety of backing plates using techniques like indium bonding, elastomer bonding and silver-filled epoxy, ensuring excellent thermal conductivity and long-term performance. Customisation is our strength, whether you need a 2-inch target for a lab-scale deposition system or a 1-metre rotatable target for industrial production, we deliver with speed and precision.

In addition, we provide alumina-coated sources, ideal for reducing contamination and extending equipment life in evaporation systems. These coated crucibles and boats are increasingly popular in applications where purity and repeatability are non-negotiable.

Services That Add Value

Beyond materials, Testbourne offers a range of services designed to support clients at every stage of their project. Our chemical analysis capabilities ensure that every material we supply meets the strictest quality standards. We use advanced techniques such as ICP-OES and GDMS to verify material composition and detect impurities down to trace levels.

We also offer refining and reclaim services, allowing customers to recover value from used targets, scrap materials and precious metal residues. This not only helps reduce costs but also supports environmental sustainability - a growing concern in both industry and academia.

For customers with unique or evolving needs, our team provides consultation and custom sourcing, leveraging our global network of trusted suppliers and manufacturing partners. Our responsive service, technical know-how and ISO-certified processes (ISO 9001, 14001 and 45001) give customers confidence that they are working with a supplier who understands both quality and compliance.

Why Choose Testbourne?

Our clients return to us because they know they can count on more than just a delivery; they count on partnership. From fast turnaround quoting and international shipping to technical support and long-term supply agreements, we take pride in being flexible, reliable and knowledgeable.

With many of our customer relationships lasting over a decade, it’s clear that what we offer goes beyond the materials themselves.
