一种6061铝合金及其加工方法
摘要：
本发明涉及一种6061铝合金及其加工方法，属金属材料领域。其加工方法包括以下步骤：对6061铝合金的原料进行熔炼、精炼，铸造，均匀化处理以及挤压。原料包括0.65‑0.7wt％的Si、0.25‑0.35wt％的Fe、0.18‑0.23wt％的Cu、0.1‑0.15wt％的Mn、0.85‑0.9wt％的Mg、0.15‑0.25wt％的Cr、0.08‑0.12wt％的Ti以及0.15‑0.2wt％的稀土铈锡，余量为Al。该加工方法简单，易操作，能有效降低6061铝合金的挤压裂纹。由此得到的6061铝合金质量好，在高达6m/min的挤压速度下不产生裂纹。
摘要（英）：

The invention relates to a 6061 aluminum alloy and a processing method thereof, and belongs to the field of metal materials. The processing method comprises the following steps of smelting and refining raw materials of the 6061 aluminum alloy, casting, homogenizing and extruding. The 6061 aluminum alloy is prepared from the raw materials in percentage by weight 0.65 to 0.7 percent of Si, 0.25 to 0.35 percent of Fe, 0.18 to 0.23 percent of Cu, 0.1 to 0.15 percent of Mn, 0.85 to 0.9 percent of Mg, 0.15 to 0.25 percent of Cr, 0.08 to 0.12 percent of Ti, 0.15 to 0.2 percent of rare earth cerium tin, and the balance Al. The processing method is simple and easy to operate, and extrusion cracks of the 6061 aluminum alloy can be effectively reduced. The obtained 6061 aluminum alloy is good in quality and cannot produce cracks at the extrusion speed of 6m/min.
