  ALUMINUM IS A LIGHTWEIGHT NON FERROUS ALLOY WITH A DENSITY OF ABOUT 2700KG/M3. THIS WONDERFUL ALLOY HAS SELF HEALING CAPABILITIES WITH REACTION TO ATMOSPERIC OXYGEN OVER TIME TO FORM A THIN LAYER OF ALUMINUM OXIDE ON THE EXTERNAL SURFACES OF THE MATERIAL TO COUNTERACT THE POSSIBILITIES OF MINOR CORROSION. THIS PHENOMENON IS WIDELY ALSO KNOWN AS OXIDATION. MANY TIMES, PEOPLE HAVE MISUNDERSTOOD THAT THIS IS A UNSIGHTLY SURFACE DEFECT THAT WILL PROBABLY AFFECT THE MECHANICAL INTEGRITY OF THE MATERIAL. BUT, ON THE CONTRARY, THIS ASPECT IS BENEFICIAL AS THE THIN ALUMINIUM OXIDE LAYER WORKS ON THE SAME PRINCIPLES OF ANODIZING IN THAT IT PROTECTS THE SURFACES OF THE MATERIAL FROM MINOR CORROSION AND ENHANCES THE DURABILITY OF THE ALUMINUM.RESEARCH OVER THE YEARS HAVE SHOWN THAT ONE METHODOLOGY TO PROMOTE THE ONSET OF OXIDATION IS BY IMMERSING THE PRODUCT INTO 100 DEGREES CELSIUS BOILING WATER. THE AFTER EFFECTS IS ALSO KNOWN AS THE “BOHEMITAGE” EFFECTS. FOR INSTANCE, IN THE APPLICATIONS OF WALL CLADDING PANELS, ALUMINIUM IS FOR INSTANCE WIDELY USED TO REDUCE THE DEAD LOAD OF THE ENTIRE ASSEMBLY OF THE STRUCTURAL COMPONENTS AS COMPARED TO OTHER METALS AND THUS IMPROVING THE OVERALL SAFETY ASPECTS.IT WAS REPORTED THAT ALUMINUM ALLOYS CONTAINING MAGNESIUM HARDENER (5000 SERIES) WORKS BEST IN CRYOGENIC CONDITIONS AND NOT SUITABLE FOR USAGE IN ROOM OR ELEVATED TEMPERATURES OVER TIME. SCIENTISTS AND ENGINEERS HAVE DISCOVERED THAT THE ALLOY WILL AGE SOFTEN OR LOSE ITS MECHANICAL STRENGTH OVER TIME UNDER ELEVATED TEMPERATURES. HENCE, ROLLING MILLS CAME UP WITH A NEW IDEA TO COUNTERACT THIS PROBLEM. FOR 5000 SERIES ALLOYS TO BE USED IN ELEVATED TEMPERATURES, H3X IS RECOMMENDED AS HEAT TREATMENT PROCESS STABILIZING WILL PREVENT THIS PHENOMENON FROM HAPPENING. AS FOR CRYOGENIC CONDITIONS, 5000 SERIES ALLOYS CAN USUALLY BE USED IN ANY TEMPERS DEPENDING ON APPLICATIONS. Show less
