PZP Steel Tyre Cord Analysis
ASTM 1070 Steel Tyre Wire
There are approximately 2.5 pounds of steel belts and bead wire in UK sourced passenger car tyres. The material is high carbon steel with a nominal tensile strength of 2,750 MN/m2 and the following typical composition:
|STEEL BELTS||BEAD WIRE|
|Carbon||0.67 – 0.73%||0.60% min.|
|Manganese||0.40 – 0.70%||0.40 – 0.70%|
|Silicon||0.15 – 0.03%||0.15 – 0.30%|
|Phosphorus||0.03% max.||0.04% max.|
|Sulphur||0.03% max.||0.04% max.|
|COATING||66% Copper/34% Zinc||98% Brass/2% Tin|
Steel from Scrap Tyres
Consumer and supplier to agree upon preparation for transport, such as the following:
Loose – Chopped. If wire is chopped or shredded, parties may wish to specify the means of processing and/or characteristics of the final product (density, length of pieces, etc.).
ISRI Code No. 272
Item: Processed tire wire (Ferrous) – Grade 1. Chopped. Less than two percent (<2%) rubber/fibre.
PYReco tyre shred is less than 1% contaminant and that contaminate is carbon char which can be shaken off the wire.
