Grade 15 Babbitt Metal vs. Type 4 Magnetic Alloy

Grade 15 Babbitt Metal belongs to the otherwise unclassified metals classification, while Type 4 magnetic alloy belongs to the nickel alloys. There are 15 material properties with values for both materials. Properties with values for just one material (15, in this case) are not shown.

For each property being compared, the top bar is grade 15 Babbitt Metal and the bottom bar is Type 4 magnetic alloy.

Grade 15 (L53620) Lead-Base Babbitt Metal Type 4 (2.4545, N14080) Nickel-Iron Soft Magnetic Alloy
