The usual forging temperature of AlMgSi1 is from 470 to 520° C. The heat quantity supplied is, however, considerably higher than the forming work. In general, 85% of the forming energy transforms into heat.
Due to the very high thermal conductivity of aluminum it is necessary to forge aluminum in heated dies. The tool temperature should be from 250 to 300° C. Also, a 5-kg aluminum billet must have gone through all forming operations of hot forming within 40 seconds; otherwise coarse grain formation begins.
Coarse grain formation beginning on the outer skin due to heat absorption results in aluminum components having a far lower dynamic loading capability than steel components. However, by intermediate heating or artificial heating, coarse grain formation is kept under 1 mm on the edge surface.

通常锻件温度AlMgSi1 是从470 对520. C 。热数量被供应是, 然而, 可观地更加高级比形成的工作。总之, 85% 形成的能量变换成热。由于铝非常高导热性它是必要伪造铝在激昂的模子。工具温度应该是从250 对300. C 。并且, 5 公斤铝宿营一定审阅热形成的所有形成的操作在40 秒钟内; 否则粗面形成开始。粗面形成起点在外皮由于热吸收导致铝组分有更低的动态装货能力比钢组分。但是, 由中间热化或人为热化, 粗面形成被保留在1 毫米之下在边缘表面。
