The most important feature is its suitability for the manufacturing process. For example, when mixing, milling and spray drying in aqueous media must be used the water-soluble binder and paraffins are excluded. In the dry blending and mixing in kerosene are inversely they paraffins (waxes) better.

Second most important requirement for the binder in powder metallurgy is the following: Binder must be possible perfectly  evaporate in vacuum (the less carbon remains after the evaporation of binder, the better).

As a water-soluble binder are often taken a following aqueous solutions: polyvinyl alcohol (PVA) and polyvinil acetat (PVAc). As a non-water soluble many different hydrocarbons (paraffins) come into question.

Any binder for copper alloy powders?

Any binders for FES2 to improve uniform in thickness of the pellet and green strength of the pellet.

Any binder for high temperature binding for mix metals? And I want to do sintering after that.
