WRITE-UP INFO OFHC COPPER WIRE ROD PRODUCTION

　

INTRODUCTION

　

ABOUT US: TAWIN MANUFACTURES Oxygen Free (OFHC) high conductivity copper wire rod 8mm diameter by well known upcast technology from outokumpu castform oy Finland.
PRODUCTION CAPACITY: 12000 MTPER ANNUM
NUMBER OF STRANDS: 16
PERFORMANCE: 99.8% HIGH YIELD
SIZE OF ROD: 8mm DIA DIRECT CAST
SPECIFICATION: ASTM B 170-89
OXYGEN CONTENT: LESS THAN 10PPM FOR CU-OF 
LESS THAN 5PPM FOR CU-OFE (FOR ELECTRONIC GRAD)
COPPER CONTENT: 99.95% TO 99.99%
HIGHLIGHTS:
  • LOW OXYGEN CONTENT
  • LOW IMPURITY CONTENT 
  • IMMUNTIY TO BYDROGEN EMBRTTLEMENT (EXCELLENT WELDABILITY, BRAZABILITY AND SOLDERABILITY)
  • GOOD FATIGUE STREBGTHl 
  • EXCELLENT IMPACT STRENGTH AND FLOW CHARACTERISTICS
  • GOOD WORKABILITY
A. COMPOSITION

B. PHYSICAL PROPERTIES REFER ANNEXTURE-1

C. MECHANICAL PROPERTIES

D. FORMING PROPERTIES
UPCAST PROCESS: REFER ANNEXTURE-2
　

　
ADVANTAGEOUS COMPARED TO OTHER COPPER RODS:
UPCAST 8MM DIA OF ROD AVOIDS ANY ADDITIONAL TREATMENTS SUCH AS BAR PREPARATION, HOT ROLLING AND PICKLING.
  • UPCAST COPPER WIRE ROD HAS SINGLE PHASE COLUMNAR GRAIN STRUCTURE WITH THE IMPURITIES IN THE SOLID SOLUTION. AFTER THE FIRST ANNEALING IN THE ROD BREAKDOWN MACHINE, THIS STRUCTURE IS RECRYSTALLIZED TO A FINE GRAIN STRUCTURE SIMILAR TO THAT OF CAST & ROLLED PRODUCT.
  • OF COPPER IS UNQUESTIONABLY THE MOST DUCTTLE OF ALL COPPER GRADES MAKING IT IDEAL MATERIAL EVEN FOR MOST DEMANDING APPLICATIONS, LIKE DRAWING TO ULTRA FINE WIRE SIZES.
  • OF ROD IS BRIGHT AND CLEAN
  • OF ROD HAS EXCELLENT ELELCTRICAL CONDUCTIVITY AND PERFORMS SUPERBLY IN ALL STANDARD CABLE AND TELECOMMUNICATION USES, MAGNET WIRES ETC.,
