Specifications require non-metallic aircraft pulleys to be made from reinforced phenolic resins that have been cured under heat, pressure and time into a uniform stable product. Ralmark Company uses a specially engineered grade of laminated phenolic exceeding the specification material performance requirements. Aluminum aircraft pulleys are manufactured from aircraft-grades of aluminum alloys.
