BRASS - STEEL - BRASS

Multilayer strips CuZn35 St CuZn35 Technical Requirements (H65/IF/H65,C2700/IF/ C2700)

Production process:
Cold rolling and rolling composite

Description
Multilayer bimetal strip CuZn35-St-CuZn35is made of low-carbon steel strip, clad on both sides with CuZn35.

Composition

	H1	BRASS CuZn35
H		STEEL
	H2	BRASS CuZn35

Base - low-carbon quality steel, grade IF(Interstitial Free Steel)/SPHC/ DC04, with chemical composition acc. to GBT3524-2015,
Hot-rolled carbon and low alloy structural steel strips
Coating - brass CuZn35 with chemical composition acc. to GBT3524-2015,.

The thickness of cladding layers h1 and h2 is the same for both sides and varies from 4 to 6% of the finished strip thickness. Upon customer's request, the thickness of the cladding layer can be up to 10% on each side.

Classification and range
By state of material:

soft - Annealing ,HV90-110,
half-hard ,HV 110-140
hard - T,HV 160-180

By type of edge:

sheared edge - O
mill edge - Н
