A saxophone ligature screw can be made of various materials, including brass, stainless steel, or nickel. The choice of material for the ligature screw can affect its durability, corrosion resistance, and overall quality.
Brass ligature screws are common and often come with the saxophone or ligature. They are relatively inexpensive and provide a good balance of durability and functionality. Stainless steel ligature screws are also popular and offer superior corrosion resistance and durability compared to brass.
Nickel ligature screws are another option that some players prefer due to their smooth texture and the fact that they don't require as much tightening as brass or stainless steel screws. However, nickel ligature screws are less common than brass or stainless steel screws and may be harder to find.
Ultimately, the choice of material for a saxophone ligature screw depends on the player's personal preference, budget, and the desired level of durability and corrosion resistance.
