The range will be decreased. How much it will be decreased will depend on several factors, perhaps most notably e.g. your aluminium box. A lot of different boxes exist, and they will/might have different openings, different seal materials, different wall thickness, different wall alloys etc.
Bottom line is, placing an RF transceiver inside a metal box is generally bad as it acts like a faraday cage.

Okay i got it now. I better use the plastic one. my idea is to create a mesh network using either NRF24L01 or NRF52480. which one is better designing, our own pcb or buying the small module? I am very confused, need help to design a mesh network.
My Application: We have 200 nodes speaks with one coordinator(we will fix them in a small play grounf). Every node task is to take the data from the sensor(through either SPI or I2C, Take any movement sensors) whenever an activity occurred and sends it to the Coordinator. Coming to the range is 100 to 200 meters. So how can i design the network using this nrf with minimal power consumption?. How mesh network works with nrf?
How many nodes we can connect? many to one / one to many? what is the limit per node. If not aluminium what material i can use for the best range(it should be very strong as vehicles may drive on them)?
