70% copper, 20% tin, 10% other metals
The Liberty Bell’s metal composition is misstated here. The National Park Service says it is about 70% copper and 25% tin, with only small amounts of other elements.
Full reasoning
This composition does not match the National Park Service’s current description of the Liberty Bell.
On the official NPS Liberty Bell page, the park states: the bell "is made of bronze" and "It's 70% copper, 25% tin and contains small amounts of lead, gold, arsenic, silver, and zinc." That directly contradicts the article’s claim that the bell is 20% tin and 10% other metals.
A separate NPS fact sheet on the bells and clocks of Independence Hall likewise describes the Liberty Bell’s composition as predominantly copper and tin with some zinc and minute traces of antimony and silver, which is consistent with only a small remainder beyond copper and tin—not 10%.
So the article understates the tin content and overstates the amount of "other metals."
