Aluminium and aluminium alloys

Aluminium alloys offer an impressive combination of low weight, good conductivity and corrosion resistance. Thanks to their high formability and good thermal properties, they are mainly used in the following areas:

• Reflectors & Sensor carriers
• Circuit board elements
• Lightweight structural components in the watchmaking industry
• EMC-compatible housings or shielding

Variants available cover both pure aluminium grades (e.g. EN AW-1050) and alloyed materials (e.g. EN AW-5052 or AW-7075) – depending on the desired combination of strength, formability and conductivity.

Tungsten and tungsten alloys

Tungsten is an exceptionally dense and temperature-resistant material with one of the highest melting points of all metals (~3420 °C). In alloy form, it is indispensable in applications with extreme requirements:

• Heavy metals for mass balance weights
• Contact and electrode materials
• X-ray and radiation protection components
• Watch technology (e.g. rotors, inertia elements)

Tungsten alloys (e.g. W-Ni-Fe, W-Cu) offer higher toughness and better workability compared to pure tungsten, combined with high density and mechanical stability.

Variety of materials for precision applications

In addition to the major material groups, Jacques Allemann also offers selected special alloys and rare materials – always tailored to:

• Precision engineering requirements
• Process compatibility (e.g. etching, electroplating, lasering)
• Compliance with standards (ASTM, ISO, EN, material numbers)

Whether in watchmaking, sensor technology, microtechnology or medical components: choosing the right alloy is crucial for function, long-term stability and aesthetics.
