Electronic Industry Thermal Spray Coatings

Electronics are everywhere. Consumers around the globe use computers, smartphones, tablets, audio and video equipment, navigation systems, appliances, and telecommunications devices. Semiconductors, conductors, chips, sensors, and processors ensure these devices function safely and reliably. Astro Alloys Inc. develops and delivers high-quality, long-lasting thermal spray coatings that effectively and efficiently protect and preserve electronic components and semiconductors from the most extreme conditions.

Thermal spray coatings for electronic components enhance the material properties of parts to help resist wear and tear, prevent corrosion, and improve overall endurance and performance. Durable and reliable electronics thermal spray coatings also prolong the life of semiconductors and other components, which decreases downtime for repairs and maintenance, saves you money, and increases productivity.

Coatings For The Electronics Industry

Thermal spray coatings for electronic components can include a wide variety of materials, usually copper and aluminum, to provide different degrees of electrical conductivity.

For the electronics industry, Astro Alloys supplies aluminum oxide, Almunia-titania, and yttrium oxide thermal spray powders effective to combat corrosion, prevent wear and tear and extend the service life of electronics devices and parts.

Aluminum Oxide Powders

Aluminum oxide thermal spray powder provides dense, hard, wear-resistant coatings with electrical insulating properties. Saint-Gobain’s alumina thermal spray powders resist thermal shock and have excellent dielectric properties.

Alumina Titania Ceramic Powders

Alumina Titania thermal spray powders feature dense, hard coatings engineered to resist wear due to abrasion, fretting, cavitation, corrosion, particle erosion, and more. By combining aluminum and titanium oxides, a smooth, wear-resistant coating is formed.

Yttrium Oxide Powders

Available in high purity and ultra-high purity, Yttria Oxide thermal spray powders offer excellent dielectric properties and protect against gas erosion in semiconductor and other electronics applications.
