Grain-Oriented Nippon Steel Z10 Silicon Steel Transformer Core Lamination 0.27mm, EI76/86/96/114

Brand new Japanese Kawasaki Nippon Steel Z10 transformer silicon steel lamination, 0.27mm thick, available in 76/86/96/114 stacks, grain-oriented. Price is per kilogram. Note: we also sell 0.23mm and 0.35mm-thick silicon steel.

This 0.27mm-thick core is grain-oriented with very high permeability (up to 1.91T) and very low core loss (only 0.72W/kg). It is an ideal electromagnetic material for high-end audio output transformers, drive transformers and power transformers. To improve transformer parameters – high efficiency, low noise, low heat – we strongly recommend inserting the laminations one by one in the grain orientation direction, as our core is oriented. Specifications:

Price is per kilogram. Weight-to-stack-thickness conversion is as follows (allow a small margin):

The relationship between weight and stack thickness for 0.35mm is as follows (0.27mm can be slightly higher):

EI66 (tongue 22 mm): 0.22 kg per cm of stack

EI76 (tongue 25.4 mm): 0.29 kg per cm of stack

EI86 (tongue 28.6 mm): 0.37 kg per cm of stack

EI96 (tongue 32 mm): 0.47 kg per cm of stack

EI105 (tongue 35 mm): 0.55 kg per cm of stack

EI114 (tongue 38 mm): 0.655 kg per cm of stack

EI133 (tongue 44.4 mm): 0.85 kg per cm of stack

This grade has very high permeability (up to 1.8T) and very low core loss (only 0.95W/kg). It is an ideal electromagnetic material for tube amp output, drive and power transformers, ensuring sheet quality.

This steel is grain-oriented (crystal grains aligned) and outperforms non-oriented steel; as is well known, oriented silicon steel is better suited for transformers.
