How to choose zinc VS stainless steel die casting?

Friends, let's talk about die casting materials today! Everyone in the industrial manufacturing circle knows that precision parts cannot be separated from the die casting process. At present, zinc alloy and stainless steel are the two top players, but which one is better? Zinc die casting is economical and versatile, stainless steel is durable and resistant to tossing. 

Zinc die casting: a little money-saving expert, large quantity and full

Bosses who use Zamak zinc alloy should understand that this thing is simply an economic powerhouse:

Advantages of Zinc die casting:

• Wallet-friendly: cheaper than stainless steel, save XX million for 10,000 pieces!

• Naturally anti-corrosion: After adding aluminum/magnesium buff, it is comparable to "metal sunscreen"

• Detail maniac: The fluidity is as smooth as milk tea, and even the most complex patterns can be poured out

• Mass production king: Thousands of pieces a day are produced as if it's a game

• Easy to process: Softer than stainless steel, the masters all say "It's like cutting butter"

• Less installation and less modification: One part can replace three parts of others

Shortcomings warning of Zinc die casting:

✖️ Weak strength: Compared with stainless steel, it's like a primary school student vs. a fitness coach

✖️ Afraid of hot hands: Start to "break down" when it exceeds 200℃

✖️ Chemical phobia: Immediately "broken" when encountering acid and alkali

✖️ Overweight: One circle fatter than the same aluminum alloy

Stainless steel die-casting: The king of hard work, specializing in treating disobedience

If you want parts as heirlooms, look here, this buddy's main slogan is "My fate is determined by me, not by God":

Highlight moments of Stainless steel die-casting

• Titanium alloy hardness: still looks good even after ten years of being beaten

• Built-in anti-rust bell: can live peacefully even in seawater

• Hell mode clearance: -200℃ to 800℃

• Skin management master: mirror finish when leaving the factory, saving polishing money

• Variety Star: 304/316... you can always find your favorite model

Points to discourage:

⚠️ Price assassin: the mold fee alone is enough to buy a Wuling Hongguang

⚠️ Operation discouragement: don't touch this "metal ancestor" without ten years of skill

⚠️ Fitness equipment: two kilograms heavier than zinc parts of the same size

⚠️ Tool control: special knives are so expensive

Choose strategies between zinc & stainless steel die casting

The entangled party directly copies homework:

▸ To save money + high precision → punch zinc alloy without thinking (such as mobile phone cases, door handles)

▸ To be durable + corrosion-resistant → buy stainless steel with your eyes closed (chemical pipelines, surgical instruments)

▸ Adults need all → Stainless steel for key parts, zinc alloy for the rest (save 30% cost!)

Last time I did a project for a car factory, I saved 150,000 yuan by using zinc alloy for the door locks, but the engine bracket must be stainless steel - this money can't be saved!
