Proper material selection in auto industry can increase fuel efficiency by 7 per cent, according to Confederation of Indian Industry-Corrosion Management Committee (CII-CMC).

"Material selection is crucial in many ways. With every 10 per cent of weight eliminated from a vehicle's total weight, fuel economy improves by 7 per cent. Lightweight materials offer great potential for increasing vehicle efficiency," an official of CII-Corrosion Management Committee said.

He said corrosion in automotive leads to loss of material, leading to failure and breakdowns, dimensional inaccuracy, degradation of aesthetics, deterioration of mechanical properties and increase in maintenance cost.
CII-CMC was constituted in 2006.

"Corrosion is widely recognised as one of the biggest challenges faced by automotive industry, and is probably one of the single largest factor causing exterior degradation of automotive surfaces, resulting in huge warranty claims that the automotive manufacturers have to face," CII said in a release.

It observed the estimated direct cost of corrosion across the world exceeds USD 2.2 trillion, which is about 3-4 per cent of the GDP of industrialised countries.

Corrosion accounts to a loss of about Rs 80,000 crore per annum in India, of which automotive industry accounts for Rs 4,000 crore, the release said.

It is estimated 25-40 per cent of corrosion cost could be saved by implementing proper corrosion management practices.

"Investment in preventive methods (to reduce corrosion) is more cost-effective than spending on repairs and maintenance later, which account for USD 2.5 billion and USD 6.5 billion respectively," said Kamachi Mudali, CII-Faraday Council of Corrosion Chairman and Associate Director, Corrosion Science and Technology Group, Indira Gandhi Centre for Atomic Research, Kalpakkam.
