Published: 01 March 2020
... ISO 185/JL/150 is an unalloyed low-tensile-strength gray cast iron that has high carbon and silicon contents, and thus the highest thermal conductivity and damping capacity. It is, therefore, useful in situations where high thermal conductivity, damping capacity, and machinability are important...

... ISO 185/JL/225 is an intermediate-tensile-strength gray cast iron that has a predominantly pearlitic matrix, and a tensile strength of 225–325 MPa (33-47 ksi), when determined on test pieces machined from separately cast, 30 mm (1.2 in.) diameter test bars. Compared with the lower strength gray...
