The Effect of Modulus and Thermal Diffusivity on Sintered Metal Performance

Sintered materials were used in some of the earliest friction applications, however paper materials have displaced most sintered materials due to their cost and performance advantages. The sintered materials continue to be used in many applications because of their high thermal diffusivity, while paper materials are often the friction material of choice because of their low modulus. A new material has been developed that combines many of the advantages of paper materials as well as advantages of sintered materials. The new sintered material, 1340V2, has the thermal diffusivity of a sintered material and the modulus of a paper material. The unique combination of low modulus and high thermal diffusivity gives 1340V2 a superior ability to dissipate and distribute the heat of engagement. This allows 1340V2 to be a candidate for severe or “oil-starved” applications and has less tendency to cause hot spotting of the reaction plates.
