Forged Aluminum Engine Piston: AL2618-T61 High-Performance Piston Forging
The forged aluminum engine piston is the core component of an internal combustion engine that carries combustion pressure and drives the connecting rod. It consists of the crown at the top, pin bosses on both sides and a skirt below. Pistons work under high temperature, high pressure and fast reciprocating motion, so they must combine high-temperature strength, fatigue resistance and low weight.
Al Forge Tech (AFT) hot forges pistons in AL2618 aluminum with special heat treatment to the T61 temper, and has supplied forged pistons for high-performance sports-car engines. 2618 is a heat-resistant 2xxx alloy that retains good strength at elevated temperature and is widely used for performance pistons. After forging, the crown, ring grooves, pin bore and skirt are CNC-machined and turned, and dimensions, hardness and composition are verified with CMM, hardness testers and a spectrometer.

Forged Aluminum Engine Piston Manufacturing Process
- 繪圖評估與 DFM我們確認合金、載荷方向和關鍵尺寸，然後執行 QForm 模擬，以預測金屬流動和缺陷風險。.
- 設計與製造銑刀組數（例如，阻斷刀和完成刀）視零件的複雜程度而定，銑刀輪廓則使用便攜式3D掃描儀進行檢查。.
- 熱鍛造600T–8,000T 熱鍛造壓 Presses 的閉式成形技術創造出持續的晶粒流，並遵循零件的輪廓。.
- 熱處理T4 溶液處理和 T6 人工老化處理均在廠內進行，參數由合金和強度要求設定。.
- CNC加工 以及完成孔、螺紋和接合面均經過機械加工，然後根據需要進行拋光、振動拋光、噴丸或陽極氧化處理。.
- 檢查與運輸尺寸、硬度及化學成分均通過 CMM、硬度測試儀及分光光度儀進行驗證，且所有批次的產品均遵照 IATF 16949 的標準進行追蹤。.
常見問題
Why are high-performance engine pistons often forged from 2618 aluminum?
The piston crown is directly exposed to combustion heat, and ordinary aluminum alloys lose strength significantly at high temperature. 2618 is a heat-resistant alloy that maintains better strength and creep resistance when hot, and forging gives a dense structure with continuous grain flow and better fatigue resistance than a cast piston. Turbocharged, high-revving and racing engines therefore often use forged 2618 pistons.
What does T61 heat treatment do for a forged piston?
T61 is a temper in which artificial aging under specific conditions follows solution treatment, balancing strength with dimensional stability at temperature so the piston changes less in size through repeated heating and cooling. AFT has in-house T4 solution and T6 aging equipment and has produced AL2618-T61 forged pistons with special heat-treatment conditions; actual parameters follow the customer’s specification.
Can Al Forge Tech supply the Forged Aluminum Engine Piston from forging through machining?
Yes. Forging, heat treatment, CNC machining, surface finishing and inspection are integrated in one facility: 52 CNC machining centers (40 four-axis and 12 4.5-axis), 30 lathes (14 with robotic loading), plus broaching, burnishing and centerless grinding. The Forged Aluminum Engine Piston can be delivered as a forged blank, semi-finished or fully machined part.
How do you keep the Forged Aluminum Engine Piston consistent from lot to lot?
Al Forge Tech runs incoming (IQC), in-process (IPQC) and final (FQC) inspection under IATF 16949:2016, supported by 4 Zeiss CMMs, hardness testers, a spectrometer and a fluorescent penetrant inspection line. First, middle and last pieces of every lot are checked against the die; when wear causes dimensional drift, the die is reworked to keep the Forged Aluminum Engine Piston stable across lots.
How are MOQ and lead time for the Forged Aluminum Engine Piston determined?
MOQ and lead time depend on part size, number of die sets, alloy and machining scope, and are confirmed in the quotation after drawing review. The typical sequence is die development, forged samples, sample approval and then mass production. Sharing your annual volume and call-off schedule helps us plan dies and capacity for the Forged Aluminum Engine Piston.
