estbourne Ltd is a professional high technology / materials company, supplying high purity materials, single crystals & wafers, evaporation sources, ceramic to metal components, thin film measuring and control, sample preparation and industrial microwave equipment. Established in 1978 they have many of experience with metals, alloys and compounds, in a variety of market areas including glass coatings, electronics, energy, defence, semiconductors, decorative & hard wearing coating industries, government research establishments and universities.

We can offer a wide range of high-purity materials for vacuum deposition. These include pure elements, alloys and compounds in a variety of forms. Please contact us for pricing and delivery times.

The materials guides from Mantis Deposition offer advise on depositing pure elements using their QUAD e-beam evaporator or their CUSP sputter deposition source.


Pure elements

We offer a large range of pure elements in the form of wires, foils, sheets, powders, rods, pellets, granules, discs and sputtering targets. We are also able to supply crucibles, cones, ribbons and even mesh. Please contact us for pricing giving full details of the material, purity, dimensions, any special tolerances and the quantity required.

Inorganic compounds

We supply a large range of inorganic compounds for R&D and production customers. Most compounds can be supplied in a variety of forms: powders, pieces, tablets, liquids and in a range of purities and sizes. We give purities based on total metallic impurities, unless otherwise stated. All materials are supplied with the appropriate Material Safety Data Sheets and Certificate of Analysis, relevant to the lot number supplied. The Certificate of Analysis typically lists metallic impurities only.

Precious metals

We can supply a wide range of precious metals including gold, palladium, platinum, silver, and many precious metal based alloys. They are available in various forms, most common Sputtering Targets, Wires, Pellets and Granules. The standard purity is typically 99.99% pure, however Gold is now available in 99.999%, other purity grades are available upon request.
We offer a reclamation service for our customers on all precious metals. Precious metal targets, either bonded or un-bonded, may be reclaimed. After refining of the spent material, we will either issue a credit or off-set against a new order. Please ask for details.


We have available an almost infinite number of alloy combinations. Most of these alloys can be supplied in powder, lump, pellet, rod, sheet and sputtering target form.


Sputter targets

Pure metal targets

We offer an extensive range of metal targets in sizes ranging from 1 inch in diameter to several meters long rectangular plates. Sputter target materials can be generally supplied within the purity range of 99% to 99.9999% but the higher purities are more material dependent.

Alloy targets

Advancement in alloying techniques by our suppliers means we can offer a wide range of targets with particular emphasis on specialty custom fabricated alloys.

Compound targets

The compounds we can supply include: oxides, nitrides, borides, sulphides, selenides, tellurides, carbides and titanates in crystalline and composite mixtures.


We can supply sputter targets bonded to copper backing plates using either metal or elastomer bonding techniques.
