Because copper is mildly posionous. The tin layer prevents copper from leaching into the food.
Brass is an alloy that contains copper, so the same reason applies there.
The coating of tin helps to prevent the copper and brass utensils from corrosion and tarnishing. It also provides a non-reactive surface for cooking acidic foods, as copper and brass can react with certain ingredients. Additionally, the tin coating can improve the overall aesthetics of the utensils.
Brass is an alloy made from copper and zinc. leaching of metal into food is a health hazard anytime. copper has the tendency to leach into food. if you are health concious, safest cookware to use is stainless steel utensils that are food grade. i think its called as 18/8 or 18/10 stainless steel utensils.

Depends on what the usage is do you want YELLOW Brass 60% Copper 40% Zinc Or do you want RED BRASS? 85% Copper 15% Zinc
Brass is an alloy made by combining copper with zinc. It is not a nonmetal; it is a metallic alloy.
Indians have used Kansa (bronze) and brass utensils since ancient times for several reasons rooted in health, tradition, and practicality. Health Benefits: Both Kansa and brass have properties that are believed to promote health. Kansa is an alloy of copper and tin, and brass is an alloy of copper and zinc. Copper is known to have antimicrobial properties, which means that these utensils can help kill bacteria and other pathogens, promoting better hygiene and health. It’s also believed that using Kansa and brass utensils can balance the body's doshas (energetic forces in Ayurveda), promoting overall well-being. Durability and Longevity: Kansa and brass utensils are incredibly durable. Unlike clay or wood, they do not break easily and can last for generations if properly maintained. This longevity made them a preferred choice for daily use as well as in religious and ceremonial practices. Aesthetic Appeal: Both Kansa and brass have a warm, golden hue that is aesthetically pleasing. This made these metals popular for both everyday use and for special occasions. Their appearance added a touch of elegance to Indian households, and they were often passed down as heirlooms. Cultural and Religious Significance: In Indian culture, metal utensils, particularly Kansa, are associated with purity and auspiciousness. They are often used in religious rituals and ceremonies, where the act of using such metals is believed to attract positive energy. Brass utensils are commonly used in poojas (worship rituals) and for serving prasadam (consecrated food), as they are considered sacred. Thermal Properties: Brass and Kansa utensils have excellent thermal conductivity, which means they heat up quickly and evenly, making them ideal for cooking. They also retain heat for a longer period, keeping food warm. These factors—health benefits, durability, aesthetics, cultural significance, and practical utility—combined to make Kansa and brass the metals of choice for utensils in ancient Indian households.
