Zinc and Copper<\/strong><\/p>\n<p>Bell metal is an alloy of copper and zinc. It is a hard, durable metal that is used to make bells. The proportions of copper and zinc in bell metal can vary, but the most common alloy is 78% copper and 22% zinc.<\/p>\n<p>Bell metal is a good conductor of sound, which is why it is used to make bells. The alloy is also resistant to corrosion, which makes it a good choice for outdoor use.<\/p>\n<p>Here is a brief explanation of each option:<\/p>\n<ul>\n<li>Option A: Nickel and Copper. Nickel and copper are both metals that are used to make alloys. However, nickel and copper are not used to make bell metal.<\/li>\n<li>Option B: Zinc and Copper. Zinc and copper are the two main components of bell metal.
