Bondable coatings can be applied to bare wire or as a second coat over the top of any of the insulations that are offered. The amount of coating applied can be standard NEMA or JIS build or thinner amounts as required.
If a special coating or insulation is required Alleima will work with you to develop a process for its use. Alleima has, for example, developed low out-gassing, high-temperature, self-bondable coatings specifically designed for the hard disk drive industry to reduce contamination and deliver good resonance performance.

Metallic coatings
Alleima provides several types of metallic coatings such as
anodizing,electroplating and electropolishing. As a standard, Alleima offers electroplating treatments with silver, rhodium, palladium, copper, gold, fine gold, tin, and nickel. And with our ability to electroplate micro components we can make state of the art metallic coatings on very small parts but also other types of electroplating can be manufactured on request. Additionally, Alleima works with cladding and cladded alloys.
