To provide aluminum parts with previously unattainable levels of hardness, wear and corrosion resistance and permanent lubricity, we’ve developed Tufram Omega®. This new, electronic-friendly coating combines our well-known Tufram® coating with a proprietary nanoparticle for optimal electrical resistance.
Let’s take a look at what makes Tufram Omega ideal for electronics applications, and some testing results that verify its properties.
Engineered Coating for Electronics. Tufram Omega features a powerful combination of properties — harder-than steel abrasion resistance and a precise range of electrical resistance — for use in the electronics industry and many other applications. This new formula strikes a perfect balance between electrical resistivity and conductivity, and is useful in electronics applications that require a precise level of electrical surface resistance for aluminum parts. Examples include:
- Semiconductor manufacturing
- LED manufacturing
- Solar cell manufacturing
- Electronic component and device manufacturing
- Aluminum rollers and slide carriers
- Pick and place equipment
- Medical electronic instruments
- Telephone exchange equipment
- Automated handling equipment
- Exterior surfaces of spacecraft
- Commercial satellites
Tests Favorably. When engineered coatings are created, a vital step in the development process involves testing and verification by an independent laboratory. To confirm the wear resistance properties of Tufram Omega, Taber abrasion testing was performed in accordance with ASTM D4060 using a 1,000g load and CS-17 wheels. Weight loss was recorded after every 1,000, 5,000 and 10,000 cycles.
An electron microscope was then used to check if conductive nano particles were still present in the pores of the abraded area. After 20,000 cycles, the conductive coating material remained in the pores, meaning that the Tufram Omega coating experienced very little wear and is a truly synergistic coating that becomes an integral part of the aluminum substrate.
To verify surface resistance, testing was done in accordance with ANSI/ESD STM 11.11-2006, which measures surface resistance in ohms. Measurements were made using a Prostat PRS-801 Resistance System. Based on surface resistance results, the testing lab confirms that Tufram Omega is a dissipative material with surface resistance between 106 and 109 ohms/cm, providing a surface that prevents open circuits and static buildup.
The new coating is now available as an off-the-shelf formula and is being used in several different applications and industries.
