Hello,
My typical design practice is to install 300 series stainless wire thread inserts in wrought aluminum plates and use high strength steel fasteners for bolted assemblies. The stainless wire thread inserts provide a durable/repairable internal thread in the expensive/complex machined wrought aluminum part. Our typical design practice is to apply a two part epoxy primer to the hole when the wire thread insert is installed to prevent corrosion. Very good field experience.
I have a new/similar design where my customer has asked me to provide an electric bond path through the fastener/insert. The fastener is steel and the stainless wire thread insert is installed in a machined aluminum plate. My customer has design experience with this type of design and applies a 'thick grey paste' to the wire thread insert when the insert is installed in the wrought aluminum plate which provides good electrical connections while assuring corrosion protection. The product my customer has identified is manufactured only in Europe. My customer is obviously in Europe.
Can someone on this forum direct me to a similar product produced/available in the US. I need aerospace (flight vehicle) grade product.
Jim
