About lead wheel balance weight

Introduction

Around the beginning of the 20th century, in the early days of the development of the automobile industry, lead began to be used in the manufacture of wheel balance weight.

The production process of lead wheel balance weight does not require machines and can be operated manually. Moreover, due to the high density of lead, it can provide a large mass in a small volume and can effectively adjust the imbalance of the wheel, which makes lead the earliest raw material for making wheel balance weight.

 

 

 

 

 

 

 

 

 

Lead wheel balance weight can be mounted on the rim by stick on or clip on to suit different wheel types and installation requirements.

 

 

 

 

 

 

 

 

 

Under normal use conditions, the lead wheel balance weight can maintain stable performance and is not easy to be damaged or fall off.

Harm of lead

Lead is toxic and can damage the nervous system, leading to intellectual retardation, memory loss, etc.; it can affect the blood system and cause anemia; it can also harm the digestive system and urinary system, etc. Long-term exposure to lead can reduce human immunity and increase the risk of disease, especially for children and pregnant women.

Reinventing Wheel balance Weights

The new law, California Health and Safety Code Sections 25215.6-25215.7, defines lead wheel weights as any weight that contains more than 0.1 percent lead. The law goes into effect on January 1, 2010 and applies when weights are installed on new vehicles or when they are removed and reinstalled during the wheel balancing process. Vehicles manufactured on or after January 1, 2010 and sold in California must use non-lead weights, and vehicles manufactured in 2009 or earlier must switch to non-lead weights when replacing or rebalancing tires. It is illegal to sell, manufacture, or install lead wheel weights in California. Violators face steep fines: $2,500 per day per violation.

Alternative to lead

With the improvement of environmental awareness, lead wheel balance weight are gradually being replaced by zinc wheel balance weight and fe wheel balance weight due to their potential harm to the environment.

Iron is a relatively common metal with relatively abundant resources and relatively low prices. During production and use, the impact on the environment is relatively small. Waste fe wheel balance weight can be recycled and reused, which is conducive to the recycling of resources.

Fe wheel weight have a higher hardness, are more resistant to wear and collision, and are not easy to deform or damage during use. Its mass distribution is relatively uniform, and it can provide a relatively stable balancing effect.

 

 

 

 

 

 

 

 

 

 

 

Therefore, fe wheel balance weight are the most popular wheel balance weight material.
