Indian Appliance Makers Swap Copper for Aluminium to Defend Shrinking Margins

Electronics and appliance manufacturers across India are replacing copper with aluminium and expanding domestic component sourcing after input inflation squeezed industry operating margins into single digits.

Producers have already raised retail prices on air conditioners, refrigerators, and washing machines by 10 to 12 percent across three rounds since January, while absorbing an additional 7 to 10 percent to protect sales volumes.

Value Engineering and Sourcing Shifts

Surging copper prices, which rose roughly 45 percent year on year, have forced appliance brands to redesign motors, connecting pipes, and coils. Replacing copper with aluminium, steel, or alternative alloys saves between 2 and 6 percent of final manufacturing costs. Strong buying from artificial intelligence data centres and electric vehicle producers has tied up global copper output months in advance.

Memory component prices have also doubled or tripled on heavy AI infrastructure demand, driving price hikes of 20 to 40 percent on smartphones, laptops, and televisions. Indian consumer electronics manufacturers import between 30 and 40 percent of their inputs, leaving factory gates exposed to higher freight rates and currency depreciation.

Supply chain snarls have caused direct revenue losses. Crompton Greaves Consumer Electricals missed out on nearly Rs 200 crore in sales during the previous quarter because of material shortages. At contract manufacturer PG Electroplast, the cost to build 500,000 air conditioners climbed from Rs 700 crore last year to Rs 940 crore.

Local Manufacturing Expansion

Brands are countering these cost pressures by shifting away from overseas suppliers. LG Electronics India now sources a key moulding resin domestically after importing its entire requirement until March, while engineering teams adjust product designs to trim material volume per unit. Voltas and Bajaj Electricals have rolled out similar value engineering programs across their appliance lineups.

Cost restructuring of this scale reflects a broader defensive pivot across Asian consumer hardware manufacturing. When consumer demand resists further retail price hikes, brands must either cut bill-of-materials costs or surrender volume in price-sensitive suburban and rural markets.

PG Electroplast plans to commission domestic production of air conditioner compressors between December and January, alongside a separate manufacturing line with an annual capacity of two million units.
