I need some help with alloy selection to braze a Fe/Ni part to a brass part. I would like a liquidus temperature of about 1000°C to 1300°C. Joint needs to be corrosion resistant. Strength should not be a problem since I am brazing the joint. I am considering aluminum alloys but do not have enough experience with brazing to know if they will suffice for my application. The alloy needs to be available in paste form. Any ideas would be appreciated. Thanks.
