Heat transfer surface typically consists of aluminum fins extruded over a liner tube, integral low finned tubing, or bare tube designs. Extended surface bearing oil coolers can provide additional cooling capacity within the same space as a bare tube bearing oil cooler. Liner tube material is normally 90/10 Cu/Ni, with stainless steel, copper, titanium and other materials available.
