The catalogues were published 5 November 2024 and their actual bodies were read 8 October 2026. Listed ranges are dated supplier catalogue information, not current inventory, a quotation or a verified combination for an order. Confirm the chosen alloy and temper, drawing, dimensions, tolerances, finish, inspection, MOQ, price, lead time, contracting company and assigned production plant in writing.
Keep identity and actual order supply separate
The introduction names 东北轻合金有限责任公司 and reports affiliation with 中国铝业集团高端制造股份有限公司. The shared group footer uses a Beijing address; it is not used here as a Dongqing factory address. A 29 July 2026 forging-project notice places that project in Harbin, Pingfang District and uses inconsistent street wording. This supports dated regional manufacturing context, not a verified street address or the plant assigned to these profile and rolled-product orders.
