Aluminum (softer than the workpiece steel) does not leave marks on aluminum, brass, and copper surfaces; it is less effective on steel where hard jaws are preferable. They are turned (bored) in situ before use to achieve maximum concentricity.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow often should aluminum jaws be replaced?\u003c\/summary\u003e\n\u003cp\u003eAluminum jaws wear out much more quickly than steel jaws — especially if used to clamp steel workpieces. Replace when: the clamping profile is irregular and does not ensure concentric grip, the material is too removed for in-situ boring. For exclusive use on aluminum and soft materials, the lifespan is acceptable; for mixed use with steel, prefer soft mild steel jaws.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDelivery times?\u003c\/summary\u003e\n\u003cp\u003eOriginal spare parts available with 3–5 working days shipping.
