ABSTRACT:
The invention provides a high-strength stamped aluminum brazed turbine for use in an automotive transmission torque converter, and a method therefor. The method includes stamping aluminum inner and outer shells each having a plurality of slots, and stamping a plurality of aluminum turbine blades having tabs. The tabs of the turbine blades are inserted into the slots of the inner and outer shell, and the tabs are bent to attach the turbine blades to the inner and outer shell. The turbine blades are brazed to the inner and outer shell with a silicon material, thereby forming a turbine of sufficient strength to operate in the powerflow path of an automotive transmission using transmission oil as its working fluid.
