PARIS (Reuters) -Visibility for aviation suppliers is improving, helped by Airbus' measures to overcome supply chain snags that hit demand in the past year, aluminium products maker Constellium said on Wednesday.

Bottlenecks in the supply chain, notably for engines, have hampered Airbus' efforts to ramp up output, though the jet maker has maintained a 2025 delivery target.

Constellium, one of the world's largest suppliers of aluminium for planes, has felt the knock-on effect with lower volumes for its aerospace business since last year.

"Things are more reassuring, we are a little less in the mist at an industrial level," Philippe Hoffmann, president of aerospace and transportation at Constellium, told Reuters at the Paris Airshow.

Boeing ( BA ), meanwhile, is also expected to accelerate deliveries once it has integrated Spirit AeroSystems ( SPR ), Hoffman said.

Increased deliveries by the two global planemakers, along with a clearing of current inventory levels, should lift demand along the supply chain within the next two years, he added.

The longer-term demand outlook for aluminium in aerospace remains healthy, with Airbus boasting orders going out over a decade for aluminium-intensive models like its A320 single-aisle jet, Hoffmann added.
