A prelubricated finstock is described for making heat exchanger fins. The lubricant is water-soluble so that it can be removed from the heat exchanger fins by aqueous means. According to the process, a coating of the water-soluble lubricant is applied to a continuous strip of aluminum alloy finstock. This coating is dried and the coated strip is coiled for shipping and storage. When used, the prelubricated finstock is uncoiled and passed through a finpress to form the heat exchange fins. The lubricant is removed from the fins by aqueous means at any stage after the finpress. |
