Alloy			Density approx.	Important tempers	Tensile Strength R_m N/mm²	Yield Stress R_p0,2 N/mm²	Elongation A %	Hardness HB	Electr. conductivity MS/s
EN-GJL-250C DIN EN 16 482	5.1203	7,2	∅ 35-50 ∅ 55-100 ∅ 105-200 ∅ 205-400	≥ 195 ≥ 180 ≥ 165 ≥ 155
Comparable Specifications: GG-25, 0.6025, DIN 1691 Electrical continuous casting made of cast iron with lamellar graphite is distinguished by its manufacturing technique with a very dense, fine, pearlitic-ferritic microstructure, in which there is an even, finely lamellar graphite distribution. This microstructure produces high resistance to friction wear with good sliding properties and is completely oil and pressure-proof, cavity-free and polishable.
