Long-Lasting and Resistant to Corrosion: Bronze can hold up well in harsh surroundings and with prolonged use. It doesn't rust easily and can withstand wear and tear, even after being exposed to different elements for years. This makes it an ideal choice for military and police equipment that needs to stay in good condition in tough situations.

Excellent for Detailed Designs: Bronze is malleable, which means it can be shaped to capture intricate designs. Whether it's small text or complex symbolic patterns, bronze ensures that every detail is clearly visible.

Versatile Surface Treatments: It can accept a variety of finishes, such as electroplating (in gold or silver), enamel coating, or painting. This enhances its visual appeal, and it's no wonder that many historical military honors and police commemorative badges use bronze to represent authority and heritage.

Great Casting Capabilities: Zinc alloy is excellent at die-casting, allowing for the creation of complex shapes, thin walls, and smooth surfaces. This makes it perfect for capturing detailed designs, like landmark images on fridge magnets or romantic patterns on wedding badges.

Various Finish Options: It can be plated (with nickel, gold, or given an antique finish), painted, or sprayed, offering a wide range of color schemes and textures. Whether you want a vintage appearance or a modern shine, zinc alloy can deliver.

Cost-Effective for Mass Production: Compared to metals like bronze, zinc alloy helps reduce costs while still maintaining good quality. This makes it ideal for large-scale orders, such as corporate promotional badges or tourist souvenirs.

Lightweight and Comfortable: Aluminum badges are easy to wear, making them great for daily accessories, event pins, or lightweight promotional items.

Easy to Process: It can be easily stamped into various shapes, allowing for efficient production when dealing with bulk orders.

Improved Durability with Anodization: Anodizing creates a hard, corrosion-resistant oxide layer on the surface of aluminum. This not only increases its lifespan but also gives it a sleek, metallic finish. It's perfect for minimalist designs where cost and weight are important factors.

Resistant to Rust and Tarnish: Unlike many other metals, stainless steel doesn't get corroded by sweat, moisture, or daily use. It keeps its shine for years.

Mirror-Like Shine: When polished, stainless steel has a glossy, mirror-like surface, adding a modern and luxurious touch to necklaces, bracelet charms, or premium badges.

Strong and Retains Shape: It has high tensile strength, which means it's not easy to bend or deform. This ensures that even delicate or frequently worn items made from stainless steel maintain their quality over time.

Purpose: For military and police gear, bronze is a great choice because of its durability. Promotional items, on the other hand, benefit from zinc alloy's cost-effectiveness.

Design Complexity: Intricate patterns are better suited for bronze or zinc alloy, while simple designs work well with aluminum.

Budget: If you're looking for an affordable option, aluminum is a good pick. For premium projects, stainless steel is the way to go.

Environment: If the item will be used outdoors or in high-moisture environments, opt for corrosion-resistant metals like stainless steel or bronze.
