Anodising Services  
   
     
  Anodising is an electrolytic process that produces a tough and corrosion resistant oxide finish on aluminium and titanium. The coating can also be coloured to produce a decorative finish.  
     
  At Frost we have invested in a high-technology production capability offering a range of sulphuric acid, chromic acid and hard anodised finishes to meet the demanding technical requirements of industries such as aerospace, defence, space and precision engineering.  
     
  Coatings are available to meet all kinds of decorative, corrosion protection, hardness, wear resistance, low friction, anti-galling and chemical resistance requirements.  
     
  Anodized coatings are complemented by a range of sealing methods. These include hot water, nickel acetate, dichromate and duplex seals and can be combined with black dye and PTFE coatings. We also offer chromate conversion coatings for short-term corrosion protection and surface passivation.  
     
  We are happy to work with customers to develop bespoke solutions for specific requirements and will invest in new plant to support this, if it leads to ongoing business.  
     
 
     
To meet the requirements of aerospace and defence customers, we are now accredited to AS9100 and obtained Nadcap in early 2010.   Quality Management System BS EN 9100:2003, ISO 9001:2000
     
We have also committed to the SC21 supply chain improvement programme.   ADS SC21
 
     
   
     
  The anodising processes on offer from Frost are:  
     
 
Sulphuric anodising Typically for decorative applications, to specifications including Def Stan 03-25, Mil-Std-171, BS1615
     
Chromic anodising Offering better corrosion protection than Mil-A-8625 Type II sulphuric acid coatings and widely used in the defence/aerospace industries. Specifications include Def Stan 03-24, Mil-A08625 Type I & IB
     
Hard anodising A thicker, tougher and harder sulphuric coating requiring precision process control and which gives a high degree of wear resistance. Specifications include Def Stan 03-26, Mil-A-8625 Type III, BS5599
     
PTFE impregnation PTFE can be incorporated during the hard anodizing process to give a low friction coating which also has good hydrophobic and lipophobic properties
 
     
   
     
  Conversion coatings include:  
     
 
Alocrom 1000 & 1200 Chromic conversion coatings giving short-term corrosion protection and meeting specification Mil-C-5541
     
Passivation To remove metallic contamination from the surface of stainless steel. Specifications include QQ-P-35, SAE AMS 2700
